Procedure

To a solution of 3-(1-cyano-1-methylethyl)benzoic acid (5.00 g, 26.4 mmol) in tetrahydrofuran (50 mL) were added oxalyl chloride (2.70 mL, 31.7 mmol) and N,N-dimethylformamide (2 drops), and the mixture was stirred at room temperature for 1 hr. The reaction mixture was concentrated under reduced pressure to give 3-(1-cyano-1-methylethyl)benzoyl chloride as a pale-yellow oily substance.
