Reaction Steps

A solution of 4-[3-(dimethylamino)methylidene-4-oxopiperidin-1-yl]-N-[3-(trifluoromethyl)phenyl]pyridine-2-carboxamide (417 mg, 0.997 mmol) in EtOH (10 ml) was treated with guanidine carbonate (719 mg, 3.99 mmol), followed by adding sodium acetate trihydrate (1.09 g, 7.98 mmol). The reaction mixture was stirred at 80° C. for 23 hours and concentrated. The residue was partitioned between EtOAc and water resulting in the formation of a yellow, amorphous solid. The solid was collected, washed with water, EtOAc, MeOH, and dried to give the title compound (59 mg, 14%).
