Procedure

To 3-cyano-5-cyclobutyl-4-methoxybenzoic acid (190 mg), toluene (2.0 mL), N,N-dimethylformamide (1 droplet) and thionyl chloride (0.07 mL) were added, and the mixture was stirred at 60° C. for 3 hours. The solvent was distilled off under reduced pressure and then azeotroped with toluene to obtain the title compound (204 mg) as a brown oily substance.
