摘要 以2-氨基苯甲腈为原料,DMF为反应试剂和溶剂,在苯磺酰氯的存在下高产率地合成了中间体亚胺啶的盐酸盐,该盐酸盐用NaOH溶液处理以后得到固态中间体亚胺啶,此中间体不须纯化,直接在乙酸中与乙醇胺或苯胺反应较高产率合成了6种标题化合物,并用IR、1HNMR和MS进行了表征。 The 2-amino-benzonitrile reacted with DMF and benzenesulfonyl chloride to give hydrochlorides of the inter- mediates, the intermediates obtained by neutralization of the hydrochlorides with sodium hydroxide solution,without purifi- cation,were directly reacted with ethanolamine or aniline in the acetic acid to from six title compounds in high yield. The structures were confirmed by IR,HNMR and MS.
