Reaction Conditions

Reaction Steps

To a solution of 2-fluorobenzaldehyde (12.4 g, 100 mmol) in DMSO (75 mL) is added p-toluenesulfinic acid sodium salt (19.6 g, 110 mmol), and the reaction mixture is heated to 100° C. for 16 h. Once complete, the reaction mixture is cooled to room temperature and poured onto ice. The product is then isolated as a white solid by filtration to afford 2-[(4-methylphenyl)sulfonyl]benzaldehyde (10.1 g, 39%).
