Procedure

5,6-Dichloro-1-methyl-1H-indazole-4,7-dione (10 grams prepared as in Example I) and cyclopropylamine (10 grams) in ethanol (50 milliliters) were stirred together at room temperature for 30 minutes. The precipitate formed was filtered off and dried to yield the desired product as a red solid having a melting point of 175°-176° C.
