A solution of 1-(ethyl-phenyl-amino)-3-methoxy-propan-2-ol (1.95 g, 9.32 mmol) and NMO (2.18 g, 2.0 eq.) in dichloromethane (15 mL) was treated with TPAP (150 mg, 0.05 eq.) at room temperature until reaction was completed. The reaction mixture was diluted with sat. NaHCO3 (50 mL) and extracted with 3×30 mL EtOAc. The combined extracts were dried over Na2SO4, filtered and concentrated and the product was purified by chromatography (10 to 15% EtOAc-hexanes) to give 1-(ethyl-phenyl-amino)-3-methoxy-propan-2-one (0.98 mg, 51%).
