5-HT 2a receptor antagonist
Useful for treating arterial occlusive disease and ischemic heart disease.
Sarpogrelate (Anplag, MCI-9042, LS-187,118) is a drug which acts as an antagonist at the5HT2A[1][2] and 5-HT2B[3] receptors. It blocks serotonin-induced platelet aggregation, and has applications in the treatment of many diseases including diabetes mellitus,[4][5] Buerger’s disease,[6] Raynaud’s disease,[7] coronary artery disease,[8] angina pectoris,[9] andatherosclerosis.[10]

Sarpogrelate hydrochloride tablets in 1993 Japan’s first listed under the tradename Anplag, is a 5-HT2 receptor blocker, can inhibit platelet aggregation, inhibition of vascular contraction, has antithrombotic effect and microcirculation. Ulcer indications for the improvement of their chronic arterial occlusive disease caused by pain, and cold ischemic various flu symptoms. -1_ {[2- (3-methoxyphenyl) phenoxy] methyl} succinic acid ethyl ester hydrochloride, the structural formula of sarpogrelate hydrochloride chemical name 2- (dimethylamino)
As follows:
Journal of Medicinal Chemistry (J.Med.Chem, 1990,33: 1818-1823) published synthetic routes as follows:
Sarpogrelate hydrochloride drug substance used in the preparation Sarpogrelate hydrochloride tablets needed to achieve acceptable purity, single hetero content must meet the corresponding requirements. US4485258 discloses a synthesis method of the first sarpogrelate hydrochloride, and recrystallized from acetone to obtain, but the experiments show that sarpogrelate hydrochloride poor solubility in acetone, acetone, hydrochloric acid is not suitable as a recrystallization solvent sarpogrelate. CN101239920A disclosed as acetonitrile, propionitrile, 1,4_ dioxane, tetrahydrofuran, dimethyl formamide, dimethyl acetamide, sulfolane, dimethyl sulfoxide or a mixture of more than two kinds thereof with methanol, ethanol, , acetone, ethyl acetate, diethyl ether, diisopropyl ether or the like can be used as the recrystallization solvent sarpogrelate hydrochloride, the purity of the product can reach 98%. And C2-C10 alkanes, C3-C10 ketones, C2-C10 carboxylic acid esters, Cl-ClO halogenated alkanes, aromatic hydrocarbons or aromatic derivative at room temperature to the reflux temperature of the hydrochloric acid solubility is small should not alone sarpogrelate as a recrystallization solvent, sarpogrelate hydrochloride, and water as a recrystallization solvent or an organic solvent, an aqueous 5% or more can not be obtained a high purity product. Existing literature does not mention the issue of a single impurity content control.

The reaction of 2-hydroxy-3′-methoxybibenzyl (I) with epichlorohydrin (II) by means of NaH in DMF gives 2-(2,3-epoxypropoxy)-3′-methoxybibenzyl (III), which by reaction with dimethylamine in refluxing THF yields 2-[3-(dimethylamino)-2-hydroxypropoxy]-3′-methoxybibenzyl (IV). Finally, this compound is treated with succinic anhydride (V) in refluxing THF and with HCl in acetone.

Specific embodiments
Example 1 Preparation of crude sarpogrelate hydrochloride [0019] Example
[0020] 1_ dimethylamino _3- [2- [2- (3_-methoxyphenyl) ethyl] phenoxy] -2-propanol hydrochloride A 250ml 13.7g plus a single-neck flask, then add water 25ml, and stirred to dissolve. With 20% aqueous sodium hydroxide to adjust PH value to 9_14, and extracted with 30ml of toluene, and the organic layer was concentrated to 50 ° C under reduced pressure until no liquid slipped 0 to give a brown oil. Of tetrahydrofuran was added 30g, and stirred to dissolve, butyryl anhydride 4.5g, was heated to reflux with stirring. After the reaction was refluxed for I~4 hours, the reaction was incubated at 40 ° C and concentrated to dryness under reduced pressure; the residue was added ethyl acetate 25g, After stirring to dissolve, the dropwise addition of saturated hydrogen chloride in ethyl acetate solution to adjust PH value to I below, was stirred 50~60min. Centrifugal filtration, was Sarpogrelate hydrochloride crude wet product. 45~55 ° C under reduced pressure (-0.08~-0.1MPa) the residue was dried to less than 0.5% of ethyl acetate to give the crude sarpogrelate hydrochloride 14.7g, yield 86%, HPLC purity 98.6%, largest single heteroatom content of 1.2 %.
