To 4-chloro-2-fluoro-3-nitro-benzoic acid (5.0 g, 22.8 mmol) suspended in dry DCM (60 mL), was added DMF (0.5 mL) followed by the slow addition of oxalyl chloride (2.4 mL, 27.3 mmol, 2M in DCM). The mixture was stirred for 2 hrs, then concentrated to yield 4-chloro-2-fluoro-3-nitro-benzoyl chloride as a yellow solid.
