Reduction with sodium tetrahydridoborate of Schiff bases derived from 3-aryl(heteryl)pyrazole-4-carbaldehydes and benzylamines gave N-benzyl-N-[3-aryl(heteryl)-4-pyrazolylmethylene]amines which were acylated with benzoyl chloride and succinic and maleic anhydrides to obtain the corresponding amides. Treatment of the title compounds with phenyl isothiocyanate afforded substituted thioureas.
用四氢硼酸钠还原由 3-芳基(杂基)吡唑-4-羧醛和苄胺衍生的希夫碱,得到 N-苄基-N-[3-芳基(杂基)-4-吡唑亚甲基]胺,用苯甲酰氯、丁二酸酐和马来酸酐酰化这些胺,得到相应的酰胺。用异硫氰酸苯酯处理标题化合物,可得到取代的硫脲类化合物。
