The crude product of 4-cyano-3-methylbenzoic acid (1.0 g) was suspended in dichloromethane. To the mixture, oxalyl chloride (1.2 g) and an catalytic amount of N,N-dimethylformamide (2 to 3 drops) were added under ice cooling. After adjusting to room temperature, the reaction solution was stirred for three hours. The solvent was distilled off under reduced pressure to obtain 4-cyano-3-methylbenzoyl chloride as a crude product (1.0 g).
