To a solution of N-(1-(4-(hydroxymethyl)phenyl)piperidin-4-yl)benzamide (1.1 g, 3.5 mmol) in CH2Cl2 (250 mL) was added TPAP (0.123 g, 0.35 mmol) and NMO (0.623 g, 5.3 mmol). After 1 hour, the mixture was filtered through Celite, concentrated, and purified by silica gel chromatography, eluting with 30% ethyl acetate/hexanes to 100% ethyl acetate, to afford N-(1-(4-formylphenyl)piperidin-4-yl)benzamide as a white solid (0.350 g, 32%).
