Reaction Steps

To a stirred suspension of 2-aminoimidazole sulfate (667 mg, 5.05 mmol) in CH2Cl2 (25 mL) was added 1,1′-carbonyldiimidazole followed by DIPEA (2.70 mL, 15.50 mmol). The resultant mixture was stirred at room temperature overnight then concentrated under reduced pressure and provided 1.53 g of imidazole-1-carboxylic acid (1H-imidazol-2-yl)-amide as a brown solid.
