By reduction of 3-aryl(heteryl)-1-phenyl-4-azidomethyl-pyrazoles in the presence of Raney nickel or by hydrazinolysis of N-[3-aryl(heteryl)-1-phenyl-4-pyrazolylmethyl]phthalimides 4-pyrazolylmethylamines were obtained that in reaction with bis(trichloromethyl) carbonate afforded 3-aryl-(heteryl)-1-phenyl-4-pyrazolylmethyl isocyanates, and with carbon disulfide furnished 3-aryl-(heteryl)-1-phenyl-4-pyrazolylmethyl isothiocyanates.
在雷尼镍存在下,通过还原 3-芳基(杂基)-1-苯基-4-叠氮基甲基吡唑,或通过肼解 N-[3-芳基(杂基)-1-苯基-4-吡唑基甲基]邻苯二甲酰亚胺,得到 4-吡唑基甲基胺,与碳酸二(三氯甲基)酯反应,得到 3-芳基-(杂基)-1-苯基-4-吡唑基甲基异氰酸酯、与二硫化碳反应可得到 3-芳基-(杂)-1-苯基-4-吡唑甲基异氰酸酯。
