実験手順

To a suspension of 9H-carbazole-1-carboxylic acid (106 mg) and 1-hydroxybenzotriazole (81 mg) in dichloromethane (2 ml) was added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (144 mg) and the mixture was stirred for 15 minutes. After adding 3-(1,2-dimethylimidazol-5-yl)aniline (94 mg) and 4-dimethylaminopyridine (92 mg), the mixture was stirred for 60 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-(2,3-dimethyl-3H-imidazol-4-yl)-phenyl]-9H-carbazole-1-carboxamide (101 mg, 53.2%).
