Procedure
To 3-cyano-4-methoxy-5-trifluoromethoxybenzoic acid (500 mg), toluene (10 mL), N,N-dimethylformamide (3 droplets) and thionyl chloride (0.28 mL) were added, and then the mixture was stirred at 60° C. for 6 hours. The solvent was distilled off under reduced pressure and the obtained residue was azeotroped with toluene and used for the synthesis of (i).
