Oxalyl chloride (0.053 ml, 0.6 mmol) was added to a stirred solution of the 3-chloro-4-[(2,2,2-trifluoroethyl)oxy]benzoic acid (D20; 76 mg, 0.30 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 solid (ca 90 mg) which was used crude in the next reaction (D48).
