実験手順

To a suspension of 9H-carbazole-1-carboxylic acid (422 mg) and 1-hydroxybenzotriazole (324 mg) in dichloromethane (10 ml) was added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (575 mg), and the mixture was stirred for 15 minutes. After adding 3-(pyrimidin-5-yl)aniline (360 mg) and 4-dimethylaminopyridine (367 mg), the mixture was stirred for 48 hours. The residue was evaporated under reduced pressure and purified by a silica gel column chromatography eluting with 2% methanol in dichloromethane to give N-(3-i din-5-yl)-phenyl)-9H-carbazole-1-carboxamide (314 mg, 43.1%).
