. In his process, a compound of formula (II)
is reacted with hydrazine to form a primary alkylamine, and then the primary alkylamine is reacted with acetic anhydride, to produce the compound of formula (I).
一种制备化合物的方法,其化学式为(I),其中Ac代表乙酸酯;X代表O或CH2;Y代表C1-C6烷基;Z选自H、卤素、CN、CHO、CF3、OCF3、OH、C1-C6烷基、C1-C6烷氧基、C1-C6硫代烷基、NH2、N(C1-C6烷基)2、NH(C1-C6烷基)、NC(O)-(C1-C6烷基)和NO2。在该方法中,化学式为(II)的化合物与肼反应形成一级烷基胺,然后一级烷基胺与乙酸酐反应,产生化合物的化学式为(I)。
