The object of the present invention is a process for preparing the 2-acetoxy-5-(2-fluor-α- cyclopropyl-carbonyl-benzyl)-4,5,6,7-tetrahydro-4H-tieno[3,2-c]pyridine (prasugrel) of the formula (I). The process starts form crystalline 5-trityl-4,5,6,7-tetrahydro-tieno[3,2- c]pyridine of the formula (VI). Further objects of the present invention are two novel crystalline forms of 5-trityl-4,5,6,7- tetrahydro-tieno[3,2-c]pyridine of the formula (VI) and the use thereof for preparing the compound of the formula (V) and process preparing thereof.
本发明的对象是一种制备式(I)的2-乙酰氧基-5-(2-氟-α-环丙基甲酰基苯基)-4,5,6,7-四氢-4H-噻吩[3,2-c]吡啶(prasugrel)的方法。该方法从晶态式(VI)的5-三苄基-4,5,6,7-四氢-噻吩[3,2-c]吡啶开始。本发明的另外目的是5-三苄基-4,5,6,7-四氢-噻吩[3,2-c]吡啶的两种新型晶体形式(VI)及其用于制备式(V)化合物的使用和制备方法。
