실험 절차
To a solution of 2-chloro-3-(1-cyanocyclopropyl)benzoic acid (16.0 g, 72.2 mmol) in tetrahydrofuran (150 mL) was added N,N-dimethylformamide (0.1 mL), and oxalyl chloride (7.2 mL, 84.0 mmol) was further added dropwise at 0° C., and the mixture was stirred at room temperature for 2.5 hr. The reaction mixture was concentrated under reduced pressure to dryness to give 2-chloro-3-(1-cyanocyclopropyl)benzoyl chloride as a pale-yellow oil.
