Reaction Conditions

Reaction Steps

To a solution of 5 g 2-(4-chloro-phenyl)-3-cyclopropylmethoxy-pyridine in 15 mL acetic acid, 3 mL hydrogenperoxyde (30% in water) was added. The reaction mixture was then stirred at 70° C. for 15 h. The reaction mixture was diluted with water and quenched with sodium carbonate. The mixture was washed with methylene chloride. The organic phase was washed with water; then dried over MgSO4 and purified by chromatography on silica gel with a gradient of ethyl acetate to ethyl acetate:methanol 4:1 to yield 3.46 g (65.19%) of the title compound as white solid, MS 276.1 (M+H)+.
