To a solution of 2-chloro-3-(1-cyano-1-methylethoxy)benzoic acid (278 mg, 1.16 mmol) produced in Example C70(iii) in tetrahydrofuran (2.5 mL) were added N,N-dimethylformamide (25 μL) and oxalyl chloride (125 μL, 1.46 mmol), and the mixture was stirred at room temperature for 1 hr. The reaction mixture was concentrated under reduced pressure to give 2-chloro-3-(1-cyano-1-methylethoxy)benzoyl chloride as a pale-yellow oil.
