実験手順

To a solution of 5-bromo-2-chloro-N-(2-oxo-ethyl)-benzamide (11.8 g, 42.5 mmol) in MeOH (400 mL) was added hydroxylamine hydrochloride (5.9 g, 85 mmol) and sodium acetate (6.97 g, 85 mmol). The mixture was stirred 18 h and the MeOH was removed in vacuo. The residue was washed with water and was dried in vacuo for 18 h and used without further purification to provide the title compound (11.7 g, 94%) as a white solid. ESMS: M+H=291.
