実験手順
To 3,5-dichloro-4-methoxybenzoic acid (8.81 g), toluene (170 mL), N,N-dimethylformamide (5 droplets) and thionyl chloride (6.0 mL) were added, and then the mixture was stirred at 60° C. for 16 hours. The solvent was distilled off under reduced pressure and the obtained residue was azeotroped with toluene and then used for the synthesis of (c).
