After a suspension of 13.3 g (50 mmol) of 1-[(4-fluorobenzoyl)amino]cyclohexanecarboxylic acid in 30 ml of acetic anhydride was stirred at 100° C. for 30 minutes, the reaction solution was concentrated under reduced pressure. Toluene was added to the residue, and the mixture was washed with water, a saturated aqueous sodium hydrogencarbonate solution and then saturated brine. After the organic layer was dried with anhydrous sodium sulfate, the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography to obtain 8.5 g (69%) of the title compound.
