2-苯乙脒盐酸盐是一种有机中间体,可由苯乙腈为原料与氯化氢反应制备得到。有文献报道其可用于制备稠环并二氮类化合物和DPP-IV抑制剂。
制备将苯乙腈(0.1 mol)投于80 mL无水乙醚中,加入无水甲醇(4.8 mL,0.12 mol),在冰盐浴中通入干燥HCl。室温下继续搅拌6小时后,减压浓缩至干,并尽可能浓干溶剂以减少HCl残留,得到白色固体。接着,在冰水浴中滴加3 M甲醇溶液(100 mL),滴毕后于室温下搅拌过夜。再次减压浓缩至干,用适量乙酸乙酯浸洗并过滤,最终烘干得到白色固体,收率为95.6%。
Synthetic routes are described for 5-phenyl-, 5-p-chlorophenyl-, 2-p-tolyl-, 2- and 4-benzyl- and 4-phenoxy-pyrimidines, each bearing a sulfur-, nitrogen- or oxygen-linked basic side chain; also to analogous biphenyls and a diphenylmethane . These compounds were required for evaluation as amplifiers of phleomycin.
