A process for the preparation of a compound of formula (I) and of a acid salt (T) wherein R1 is selected from the group consisting of alkyl, aryl, cycloalkyl, heteroalkyl, heteroaryl and heterocycloalkyl, R2 and R3, are, independently of each other, selected from the group consisting of alkyl, aryl, cycloalkyl, heteroalkyl, heteroaryl and heterocycloalkyl, R4, R5, R6 and R7, are independently of each other, selected from the group consisting of H, alkyl, aryl, cycloalkyl, heteroalkyl, heteroaryl and heterocycloalkyl, and wherein the acid salt is a 2,3-Ditoluoyl tartaric acid salt, 2,3-Dibenzoyl tartaric acid salt, 2,3-Dianisoyl tartaric acid salt, 2,3-Dibenzoyl tartaric acid mono(dimethylamide) salt or a mixture of two or more thereof, wherein the tartaric acid salt (T) of the compound of formula (I) contains at least 90 % by weight of the tartaric salt of the compound of formula (Ia) based on the total weight of the acid salt of the compound of formula (I).
一种制备化合物(I)和酸盐(T)的方法,其中R1从烷基、芳基、环烷基、杂原子烷基、杂原子芳基和杂原子环烷基组成的群体中选择,R2和R3独立地从烷基、芳基、环烷基、杂原子烷基、杂原子芳基和杂原子环烷基组成的群体中选择,R4、R5、R6和R7独立地从H、烷基、芳基、环烷基、杂原子烷基、杂原子芳基和杂原子环烷基组成的群体中选择,其中酸盐是2,3-二甲苯酰酒石酸盐、2,3-二苯甲酰酒石酸盐、2,3-二苯甲酰酒石酸盐、2,3-二苯甲酰酒石酸单(二甲酰胺)盐或两者或两者以上的混合物,其中化合物(I)的酒石酸盐(T)含有至少90%的化合物(Ia)的酒石酸盐,基于化合物(I)的酸盐的总重量。
