Procedure
470 mg (1.71 mmol) of (4-chlorophenyl)(3,3-difluorocyclopentyl)acetic acid were dissolved in 8 ml of dichloromethane, and a drop of DMF was added. At 0° C., 1.7 ml (3.42 mmol) of oxalyl chloride were then slowly added dropwise, and the mixture was stirred at this temperature for 1 h. After the reaction had gone to completion, the reaction solution was evaporated under reduced pressure and the residue obtained was taken up in 50 ml of dichloromethane and then once more evaporated to dryness. This gave 500 mg (99% of theory) of the title compound as a colourlees oil. The product obtained in this manner was used without further purification and without further spectroscopic characterization in subsequent reactions.
