To a suspension of 9H-carbazole-1-carboxylic acid (148 mg) and 1-hydroxybenzotriazole (114 mg) in dichloromethane (3 ml) was added 1-ethyl-3-(3-dimethylaminopropyl)carbodiinide hydrochloride (201 mg), and the m e was stirred for 15 minutes. After adding 5-(3-amino-4-methylphenyl)pyrimdine (136 mg) and 4dimethylaminopyridine (128 mg), the mixture was stirred for 24 hours. The mixture was evaporated under reduced pressure and the residue was purified by a silica gel column chromatography eluting with 2% methanol in dichloromethane to give N-[6methyl-3-(pyrimidin-5-yl)-phenyl]-9H-carbazole-1-carboxamide (89 mg, 33.6%).
