Versuchsvorschrift
To 3-cyano-4-methoxybenzoic acid (1.78 g), toluene (20 mL), N,N-dimethylformamide (3 droplets) and thionyl chloride (1.14 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 used for the synthesis of (d).
