A process for the production of 1R,2S-methoxamine, which comprises adding trifluoroacetic acid dropwise to a solution comprising (S)-amino-1-(2,5-dimethoxyphenyl)-1-propanone, the amino group of which is protected, and dimethylphenylsilane and removing the protecting group from the resulting amino-protected(1R,2S)-2-amino-1-(2,5-dimethoxy-phenyl)-1-propanol. Also claimed are 1R,2S-methoxamine or a physiologically tolerable salt thereof for use as a medicament, and a pharmaceutical composition comprising 1R,2S-methoxamine or a physiologically tolerable salt thereof in admixture or conjunction with a pharmaceutically suitable carrier.
一种生产 1R,2S-甲氧基胺的工艺,包括将三氟乙酸滴加到由(S)-氨基-1-(2,5-二甲氧基苯基)-1-丙酮(其氨基被保护)和二甲基苯基硅烷组成的溶液中,并从得到的氨基保护的(1R,2S)-2-氨基-1-(2,5-二甲氧基苯基)-1-丙醇中除去保护基。还要求得到用作药物的 1R,2S-甲氧基胺或其生理上可耐受的盐,以及包含 1R,2S-甲氧基胺或其生理上可耐受的盐的药物组合物,该组合物与药物上适用的载体混合或一起使用。
