Procedure

A solution of acetic acid 3-carbamoyl-6-fluoro-6-methyl-1-{2-phenyl-1-[(quinoxaline-2-carbonyl)-amino]-ethyl}-heptyl ester (522 mg, 1.03 mmol) in N,N-dimethylformamide dimethyl acetal (2 mL) was heated to 50° C. for two hours, cooled to ambient temperature and diluted with methylene chloride and water. The organic layer was washed with saturated aqueous sodium chloride, dried over sodium sulfate, filtered and concentrated to give the title compound as a white foam (580 mg, 100%).
