Reaction Steps

To 3-fluoro-4-methylsulfonyl-benzoic acid (490 mg, 2.25 mmol), sodium hydride (270 mg, 6.74 mmol), methanol (1.55 g, 2.0 mL, 48.3 mmol) was added DMF (5 mL) and reaction mixture was heated at 100° C. for 1 hour. The reaction mixture was cooled and diluted with EtOAc and acidified using 1 M HCl solution. The organic layer was separated, washed with saturated aqueous brine solution (3×), dried over sodium sulfate and concentrated in vacuo to give 3-methoxy-4-methylsulfonyl-benzoic acid (496 mg, 95%). ESI-MS m/z calc. 230.0. Found 231.3 (M+1)+; Retention time: 0.49 minutes (3 min run).
