摘要
本研究合成了达比加群酯可能存在的4个有关物质,并经1H NMR、MS和13C NMR分析确证为3-[N-[[2-[[[4-(氨基亚氨基甲基)苯基]氨基]甲基]-1-甲基-1H-苯并咪唑-5-基]羰基]-N-(吡啶-2-基)-氨基]丙酸(1)、3-[N-[[2-[[[4-[[[(己氧基)羰基]亚氨基]氨甲基]苯基]氨基]甲基]-1-甲基-1H-苯并咪唑-5-基]羰基]-N-(吡啶-2-基)氨基]丙酸(2)、2-[(4-氰基苯胺基)甲基]-1-甲基-1H-苯并咪唑-5-甲酸乙酯(3)和2-[[[4-(氨基亚氨基甲基)-苯基]氨基]甲基]-1-甲基-1H-苯并咪唑-5-甲酸乙酯对甲苯磺酸盐(4)。
Four related substances of dabigatran etexilate were synthesized, and their structures were confirmed by 1HNMR, MS and 13CNMR. They were 3-[2-[[(4- carbamimidoylphenyl)amino]methy l]-1- methyl- N-(pyridin-2- y l)- 1 H- benzo[d]imidazole- 5- carboxamido]propanoicacid(1), 3-[2-[[[4-[N ’-[(hexyloxy)carbonyl]carbamimidoyl]phenyl]amino]methyl]-1-methyl-N-(pyridin-2-yl)-1H-benzo[d]imidazole-5-carboxamido]propanoicacid(2), ethyl 2-[[(4-cyanophenyl)amino]methyl]-1-methyl-1H-benzo[d]imidazole-5-carboxylate(3) and ethyl 2-[[(4-carbamimidoylphenyl)amino]methyl]-1-methyl-1H-benzo[d]imidazole-5-carboxylate 4-methylbenzene sulfonate(4).
