Procedure
Thionyl chloride (5.68 ml) was added dropwise to a solution of 4-fluoro-3-methylbenzoic acid (10 g) in MeOH (150 mL) at 0° C. over a period of 10 minutes under nitrogen. The resulting mixture was stirred at rt for 24 h. The solvent was removed and the residue diluted with EtOAc, washed with sat. NaHCO3, brine, dried, filtered and evaporated to afford the subtitle compound, 9.85 g.
