Reaction Steps

To a solution of acetic acid 3-(dimethylaminomethylene-carbamoyl)-6-fluoro-6-methyl-1-{2-phenyl-1-[(quinoxaline-2-carbonyl)-amino]-ethyl}-heptyl ester (580 mg, 1.03 mmol) in acetic acid (2.5 mL) was added hydrazine (35 wt. % in water, 0.040 mL). The resulting solution was heated to 50° C. for 4 hours, cooled to ambient temperature, diluted with ethyl acetate, and neutralized with saturated aqueous sodium bicarbonate. The organic later was dried over sodium sulfate, filtered, and concentrated to give the title compound as a white foam (580 mg, >100%).
