Reaction Steps

To a solution of 1-(5-(tert-butyl)-2-(methoxymethoxy)-3-(6-(trifluoromethyl)pyridin-3-yl)phenyl)ethan-1-one (440 mg, 1.15 mmol) in methanol (5 mL) was added para-toluenesulfonic acid (330 mg, 1.72 mmol) and the reaction mixture heated to 40° C. After 30 minutes the reaction mixture was partitioned between ethyl acetate and saturated aqueous sodium bicarbonate solution. The organic phase was separated, dried (Na2SO4), filtered and purified by flash chromatography on silica eluting with 0-100% ethyl acetate in hexanes to yield 1-(5-(tert-butyl)-2-hydroxy-3-(6-(trifluoromethyl)pyridin-3-yl)phenyl)ethan-1-one (338 mg, 87%) as a cream colored solid.
