Reaction Steps

Acetyl guanidine (2.6 g, 25.7 mmol, 3.0 eq) was dissolved in DMF anhydrous (40 mL) and 2-Bromo-1-(4-difluoromethoxy-phenyl)-ethanone (2.3 g, 8.5 mmol, 1.0 eq) was added; the mixture was stirred under nitrogen at room temperature for 4 days. DMF was dried; the residue was washed with water, filtered and dried. The crude was crystallized from methanol to give 1.2 g of the title compound (yield: 53%).
