Reaction Steps

2-Amino-5-bromo-benzamide (2 g, 9.3 mmol) was dissolved in chloroform (40 ml) in a 50 ml round bottomed flask and cooled to 0° C. Pyridine (0.8 ml, 9.3 mmol) was added followed by 2-fluoro-benzoyl chloride (1.3 ml, 10 mmol) and the mixture was magnetically stirred for 1 hr at this temperature. 10% Hydrochloric acid (50 ml) was added and the precipitated solid was filtered, washed with water and dried to yield pure title compound (1.8 g, 57%).
