3-amino-6-chloro-indazole-1-carboxylic acid methylamide 以
吡啶 为溶剂,
反应 0.5h,
以Analogously to Example 46, 0.1 mol of 3-amino-6-chloroindazole and 0.1 mol of methyl isocyanate in 100 ml of pyridine give 3-amino-6-chloroindazole-1-carboxylic acid methylamide (melting point: 148°-150° C; 50% of theory) in 30 minutes at 10°-15° C.的产率得到3-氨基-6-氯-1H-吲唑
