Procedure

[5-(4-Bromo-phenyl)-3-methyl-isoxazol-4-yl]-methanol (1.2 g, 4.5 mmol) was treated with 4-methylmorpholine N-oxide (0.786 g, 6.7 mmol) and tetrapropylammonium perruthenate (catalytic) in CH2Cl2. The reaction was monitored by analytical LCMS and when complete it was filtered through Celite then submitted to silica gel chromatography to give the title compound.
