Procedure

Acetic acid (304 μl) and cyclopropanecarbaldehyde (406 μl) were added to a solution of 2,3-diamino-5-bromopyridine (1000 mg) in dichloromethane (25 ml) at room temperature, followed by stirring for 1 hour. Sodium tetrahydroborate (604 mg) was added to the reaction solution under ice-cooling, and the mixture was stirred with warming to room temperature for 22 hours. The reaction solution was extracted by adding a saturated aqueous sodium bicarbonate solution and dichloromethane. The resulting organic layer was washed with brine and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The resulting residue was purified by flash column chromatography to give the title compound (286 mg).
