Reaction Steps

To a solution of 2-aminobenzimidazole (1.00 g, 7.51 mmol) and pyridine (0.714 ml, 9.01 mmol) in tetrahydrofuran (25 ml) was added, under ice-cooling, 2,2,2-trichloroethyl chloroformate (1.25 ml, 9.01 mmol), and the mixture was stirred at room temperature for 1 hour and half. Water was poured to the reaction mixture, and 1.27 g (54.6%) of the desired product as a solid was separated by filtration.
