To a stirred room temperature solution of 3-fluoro-N-(4-hex-1-enyl-naphthalen-1-yl)-5-morpholin-4-yl-benzamide (2.7 g, 6.25 mmol) THF (15 ml) and water (5 ml) is added osmium tetroxide (2.5% in t-butanol) (1000 and sodium periodate (6 g) in portions over 30 minutes. After 1.5 hours, the mixture is diluted with ethyl acetate (200 ml) and washed with water (2×100 ml). The organic layer is dried over anhydrous sodium sulfate and evaporated to dryness. The residue is purified by column chromatography on silica gel eluting with 25-30% ethyl acetate in hexanes to give 3-fluoro-N-(4-formyl-naphthalen-1-yl)-5-morpholin-4-yl-benzamide as a tan powder (1.072 g).
