Reaction Steps

To a solution 2-(3,5-Dichloropyridin-4-yl)-1-{9-methoxy-spiro[2H-1,5-benzodioxepin-3(4H),4′-tetrahydropyran]-6-yl}ethanone [127] (66 mg, 150 μmmol) in CH2Cl2 (2 mL) was added 30% H2O2 (45 μL) and methyltrioxorhenium(VII) (10 mg). The mixture was stirred for 18 h, added MnO2 (10 mg) and was stirred for another hour. CH2Cl2 (10 mL) was added and the organic phase was washed with water. The combined organic phase was dried over MgSO4 and evaporated to dryness under reduced pressure. Standard HPLC purification afforded 5.6 mg of the product.
