The invention relates to a process for the preparation of Atazanavir, which comprises reacting the hydrochloride salt of compound (6)
with N-methoxycaxbonyl-L-tert-leucine, the removal of the benzyloxycarbonyl group and the reaction with methoxycarbonyl chloride. The process is particularly advantageous in that it allows to use reduced amounts of N-methoxycarbonyl-L-tert-leucine and avoids the use of unstable intermediates.
该发明涉及一种用于制备阿扎那韦的过程,包括将化合物(6)的盐酸盐与N-甲氧羰基-L-叔亮酸进行反应,去除苄氧羰基团,然后与甲氧羰基氯化物进行反应。该过程特别有利的地方在于可以使用较少量的N-甲氧羰基-L-叔亮酸,并且避免使用不稳定的中间体。
