To a stirred slurry of acidic silica gel (prepared from 36 g of silica gel, 120 ml of dichloromethane, and 6.6 ml of 15% aqueous sulfuric acid) was added 3-(dimethoxymethyl)-α-(2-fluorophenyl)-2-thiophenemethanol in dichloromethane (45 ml). The reaction mixture was stirred at room temperature for 1.5 hrs, poured over anhydrous potassium carbonate, and filtered. Concentration of the filtrate gave 2-[(2-fluorophenyl)hydroxymethyl]-3-thiophenecarboxaldehyde.
