摘要
邻氟苯乙酸乙酯经溴化得2-溴-2-邻氟苯基乙酸乙酯(2),2与2-(叔丁基二甲基硅氧基)-4,5,6,7-四氢噻吩并[3,2-c]吡啶(3)缩合再经格氏反应制得2-(叔丁基二甲基硅氧基)-5-(α-环丙羰基-2-氟苄基)-4,5,6,7-四氢噻吩并[3,2-c]-吡啶(5),5经脱保护和乙酰化得普拉格雷,总收率48%(以3计)。
Prasugrel was synthesized from ethyl 2- (2-fluorophenyl) acetate by bromination, condensation with 2- [ (tert-butyldimethylsilyl) oxy] -4,5,6,7-tetrahydrothieno E3,2-c]pyridine (3) and Grignard reaction to give 2- [ (tert- butyldimethylsilyl) oxy] -5- (α-cyclopropylcarbonyl-2-fluorobenzyl) -4,5,6,7-tetrahydrothieno [3,2-c] pyridine (5), which was subjected to deprotection and acetylation with an overall yield of 48 % (based on compound 3).
