    • A method for preparing clopidogrel is provided to obtain optically pure clopidogrel with high yield through a simple process, which is used for treating peripheral arterial diseases and ischemic heart diseases. The method comprises the steps of: (a) reacting a (Œ)-alpha-(2-chlorophenyl)-6,7-dihydro-4H-thieno[3,2-c]pyridine-5-acetic acid represented by the formula(2) with an optically active amine derivative to crystallize a salt of a partial stereoisomer thereof represented by the formula(4) and then isolating the optically active derivative from the salt to obtain (S)-(+)-alpha-(2chlorophenyl)-6,7-dihydro-4H-thieno[3,2-c]pyridine-5-acetic acid represented by the formula(3) or an acid-addition salt thereof; and (b) methyl-esterifying the compound represented by the formula(3) or the acid-addition salt thereof to obtain a clopidogrel represented by the formula(1).
    • 提供了一种制备氯吡格雷的方法,通过简单的方法获得光学纯的氯吡格雷,用于治疗外周动脉疾病和缺血性心脏病。 该方法包括以下步骤:(a)使由式(Ⅳ)表示的(Œ)-α-(2-氯苯基)-6,7-二氢-4H-噻吩并[3,2-c]吡啶-5-乙酸 (2)与光学活性胺衍生物结晶,其结晶由式(4)表示的部分立体异构体的盐,然后从盐中分离光学活性衍生物,得到(S) - (+) - α-(2-氯苯基) -6,7-二氢-4H-噻吩并[3,2-c]吡啶-5-乙酸或其酸加成盐; 和(b)使由式(3)表示的化合物或其酸加成盐进行甲基酯化以获得由式(1)表示的氯吡格雷。
