Reaction Steps

To 3-bromo-4-chloro-benzoic acid (9.4 g, 40 mmol) in dry DCM (100 mL), was added DMF (0.5 mL) followed by addition of oxalyl chloride (22.5 mL, 55 mmol, 2M in DCM) slowly. The mixture was stirred for 1 hr, then concentrated to yield 3-bromo-4-chloro-benzoyl chloride as an off-white solid.
