Reaction Steps

Cyclopropylamine (0.12 g, 2.2 mmol) in dichloromethane (3 mL) was added to a solution of triphosgene (0.22 g, 0.74 mmol) in dichloromethane (5 mL) at 0° C. under argon. Triethylamine (0.59 mL, 4.2 mmol) in dichloromethane (3 mL) was then added and the resulting mixture was stirred at room temperature for 2 hours and then cooled to 0° C. 2-Hydrazino-3-iodopyridine (preparation 26b, 0.50 g, 2.1 mmol) in dichloromethane (5 mL) was added and the resulting mixture was stirred at room temperature overnight. The solution was cooled to 0° C. and a solid precipitated. The solid was filtered, washed with diethyl ether and dried to yield the title compound (0.56 g, 83%) as a white solid.
