Reaction Steps

Oxalyl chloride (2.60 g) was added to a suspension of 2-chloro-4-fluorobenzoic acid (3.44 g) in dichloromethane (50 ml). Two drops of dimethylformamide were added and the mixture was stirred for 18 hours at room temperature. The resultant solution was evaporated to give the crude 2-chloro-4-fluorobenzoyl chloride as a viscous oil (3.72 g).
