Versuchsvorschrift

To 3-cyano-5-isopropyl-4-methoxybenzoic acid (658 mg), toluene (7 mL), N,N-dimethylformamide (2 droplets) and thionyl chloride (0.33 mL) were added, and the mixture was stirred at 60° C. for 16 hours. The solvent was distilled off under reduced pressure and then azeotroped with toluene to obtain the title compound (710 mg) as a brown oily substance.
