実験手順

5.0 g. (27.1 mMol) 6-aminoindolin-2-one hydrochloride (Helv. Chim. Acta, 20, 373/1937) are suspended in 100 ml. methylene chloride, mixed with 3.7 ml. (27.1 mMol) triethylamine and stirred for 10 minutes. While cooling with ice, 6.73 g. (37.8 mMol) isonicotinic acid chloride hydrochloride and 5.24 ml. (37.8 mMol) triethylamine are added thereto. After 3 hours, the methylene chloride is distilled off and the residue is worked up with water and filtered with suction. The residue is stirred with hot ethanol. There are obtained 5.6 g. (82% of theory) of the title compound; m.p., 315°-320° C.
