Participants

Reaction Steps

Dicyclohexylcarbodiimide (1.07 g, 5 mmol) in 20 mL CH2Cl2 is added to a stirred solution containing 1.54 g (4.7 mmol) 5-(difluoromethoxy)-2-(4-isopropyl-4-methyl-5-oxo-2-imidazolin-2-yl)nicotinic acid in 30 mL CH2Cl2 under nitrogen at room temperature. The mixture is stirred overnight, filtered and concentrated to give the product, 7-(difluoromethoxy)-2-isopropyl-2-methyl-5H-imidazo[1',2':1,2]pyrrolo[3,4-b]pyridine-3(2H), 5-dione.
