    • The present invention relates to a process for the preparation of acetyl-amidiniophenylalanyl-cyclohexylglycyl-pyridinioalaninamides of the formula I, 1 in which the anions X are physiologically acceptable anions, and their analogs, which are effective inhibitors of the blood coagulation factor Xa and which can be used, for example, for preventing thromboses. The process according to the invention comprises the coupling of 2-null2-acetylamino-3-(4-amidinophenyl)propionylaminonull-2-cyclohexylacetic acid, which is obtained from 2-null2-acetylamino-3-(4-cyanophenyl)acryloylaminonull-2-cyclohexylacetic acid by asymmetric hydrogenation and conversion of the cyano group into the amidine, or a salt thereof, with a 3-(2-amino-2-carbamoylethyl)-1-methylpyridinium salt or a salt thereof. The invention furthermore provides starting materials and intermediates for this process, processes for their preparation and acetyl-(S)-4-amidiniophenylalanyl-(S)-cyclohexylglycyl-(S)-(1-methyl-3-pyridinio)alaninamide as ditosylate salt.
    • 本发明涉及一种制备式I的乙酰基 - 脒基苯脒基 - 环己基甘氨酰 - 吡啶并吡喃酰胺的方法,其中阴离子X是生理上可接受的阴离子,以及它们的类似物,它们是凝血因子Xa的有效抑制剂, 可用于例如用于预防血栓形成。 根据本发明的方法包括2- [2-乙酰氨基-3-(4-脒基苯基)丙酰基氨基] -2-环己基乙酸的偶联,其由2- [2-乙酰氨基-3-(4-氰基苯基) 丙烯酰氨基] -2-环己基乙酸,通过不对称氢化,并将氰基转化为脒或其盐与3-(2-氨基-2-氨基甲酰基乙基)-1-甲基吡啶鎓盐或其盐。 本发明还提供了该方法的起始原料和中间体,其制备方法和乙酰基 - (S)-4-脒基苯基丙氨酰 - (S) - 环己基甘氨酰 - (S) - (1-甲基-3-吡啶鎓)丙烯酰胺作为二甲苯磺酸盐 。
