Participants

Reaction Steps

To a solution of 2-{1-[(12-cyclohexyl-3-methoxy-6,7-dihydro-5-oxa-7a-azadibenzo[a,e]azulene-9-carbonyl)amino]-1-methylethyl}-3H-benzimidazole-5-carboxylic acid (0.07 g, 0.12 mmol) in N,N-dimethylformamide (1.0 ml) were successively added 2M dimethylamine-tetrahydrofuran solution (0.30 ml, 0.59 mmol), N-ethyl-N′-3-dimethylaminopropylcarbodiimide hydrochloride (0.03 g, 0.15 mmol) and 1-hydroxybenzotriazole monohydrate (0.02 g, 0.15 mmol) at room temperature, and the mixture was stirred overnight. Saturated aqueous sodium hydrogen carbonate solution, methanol and water were added to the reaction mixture. The precipitate was collected by filtration, washed with water, and dried in vacuo to give N-[1-(6-dimethylcarbamoyl-1H-benzimidazol-2-yl)-1-methylethyl]-12-cyclohexyl-3-methoxy-6,7-dihydro-5-oxa-7a-azadibenzo[a,e]azulene-9-carboxamide (0.05 g, yield 63%).
