Reaction Steps

A catalytic amount of DMF (approximately 3 drops) was added to a stirred mixture of 4-chloro-2-iodobenzoic acid (24.47 g, 86.63 mmol) and oxalyl chloride (11.34 mL, 129.9 mmol) in DCM (100 mL) under a nitrogen atmosphere. The reaction mixture was stirred for 2 hours and then concentrated in vacuo to give 4-chloro-2-iodobenzoyl chloride as a yellow oil that solidified upon standing (26.07 g).
