Procedure

To 4-benzyloxy-3-trifluoromethylbenzoic acid (444 mg), toluene (5 mL), N,N-dimethylformamide (2 droplets) and thionyl chloride (0.16 mL) were added, and then the mixture was stirred at 60° C. for 20 hours. The solvent was distilled off under reduced pressure and then azeotroped with toluene, and the obtained product was used for the synthesis of (h).
