Procedure

Oxalyl chloride (0.040 ml, 0.460 mmol) was added to a stirred solution of 3-cyano-4-[(cyclopropylmethyl)oxy]benzoic acid (D24; 50 mg, 0.230 mmol) in dichloromethane (DCM) (2 ml) containing N,N-dimethylformamide (DMF) (0.02 ml) at room temperature under nitrogen, and the mixture was stirred at room temperature for 2 h. The solvent was evaporated in vacuo to give the title compound (54.2 mg) which was used in the subsequent step (D49) without purification.
