실험 절차
Oxalyl chloride (0.053 mL, 0.6 mmol) was added to a stirred solution of 3-chloro-4-[(cyclopropylmethyl)oxy]benzoic acid (WO 2005058848; 68 mg, 0.3 mmol) in dichloromethane (DCM) (2 ml) containing N,N-dimethylformamide (DMF) (0.02 ml) at 0° under nitrogen, and the mixture was allowed to warm to room temperature with stirring overnight. The solvent was evaporated to give the title compound as a yellow oil (ca 80 mg) which was used crude in the subsequent reaction (D46).
