    摘要: A method of purifying a salt of pemetrexed having a structure of formula (III) by salting-out, wherein if M3+ is H+, then each of M1+ and M2+ is independently H+, Li+, Na+ or K+, provided that both of them are not H+; if M3+ is Li+, Na+ or K+, then each of M1+ and M2+ is independently Li+, Na+ or K+.

    摘要翻译: 通过盐析纯化具有式(III)结构的培美曲塞盐的方法,其中如果M3 +为H +,则M1 +和M2 +各自独立地为H +,Li +,Na +或K +,条件是它们都不是 H +; 如果M3 +为Li +,Na +或K +,则M1 +和M2 +各自独立为Li +,Na +或K +。
