摘要:
A process for making the compound of formula (I) wherein Ac represents acetate; X represents O or CH2; Y represents C1-C6alkyl; and Z is selected from the group consisting of H, halogen, CN, CHO, CF3, OCF3, OH, C1-C6alkyl, C1-C6alkoxy, C1-C6thioalkyl, NH2, N(C1-C6alkyl)2, NH(C1-C6alkyl), NC(O)-(C1-C6alkyl), and NO2. 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).
