Reaction Steps

To a solution of 4-nitrophenyl chloroformate (1.06 g) in dichloromethane (15 ml) was added dropwise a solution of 1-(4-aminophenyl)-N-cyclopropyl-5-propyl-1H-1,2,3-triazole-4-carboxamide (1.0 g) obtained in Example 1d) and N,N-dimethylpyridin-4-amine (0.65 g) in dichloromethane (15 ml) under ice-cooling. The reaction mixture was stirred at room temperature for 7 hr, a solution (2M, 18 ml) of ammonia in methanol was added, and the mixture was further stirred for 10 hr. Ethyl acetate was added to the reaction mixture, and the resulting insoluble material was collected by filtration and recrystallized from methanol/ethyl acetate to give the title compound as a colorless powder (0.91 g, 80%).
