실험 절차

Into a 500-mL 3-necked round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed [2-(benzyloxy)-3-methylphenyl]methanol (30 g, 131.41 mmol, 1.00 equiv) and DMSO (300 mL). This was followed by the addition of 2-iodoxybenzoic acid (41 g, 146.42 mmol, 1.10 equiv) in several batches. The resulting solution was stirred for 2 h at room temperature. The resulting solution was diluted with 1.5 L of ethyl acetate. The resulting mixture was washed with 3×800 mL of brine. The mixture was dried over anhydrous sodium sulfate. This resulted in 30 g (crude) of 2-(benzyloxy)-3-methylbenzaldehyde as orange oil. MS (ESI) m/z 227 ([M+H]).
