Reaction Steps

Add tetrapropylammonium perruthenate (0.35 g) to a mixture of (2-fluoro-4-methylamino-phenyl)-methanol (0.18 g), 4-methylmorpholine N-oxide (0.38 g) and freshly activated powdered molecular sieves (0.30 g) in dry dichloromethane (10 mL) at room temperature under a nitrogen atmosphere. Stir for 30 minutes and add more dichloromethane and filter through a florisil-Celite® pad. Concentrate under reduced pressure to provide (0.25 g, 76%) of the title compound as an oil.
