Procedure

To 3-cyano-5-ethyl-4-methoxybenzoic acid (347 mg), toluene (3.5 mL), N,N-dimethylformamide (0.01 mL) and thionyl chloride (0.15 mL) were added, and then the mixture was stirred at 60° C. for 14 hours. The solvent was distilled off under reduced pressure and then azeotroped with toluene to obtain the title compound (387 mg) as a brown oily substance.
