Participants

Reaction Steps

To a solution of N-(1-(benzyloxy)-2-(5-methyl-1,2,4-oxadiazol-3-yl)propan-2-yl)-2-methylpropane-2-sulfinamide (example 112c, 1.2 g, 2.73 mmol) in methanol (15 ml) was added a 4.0M solution of hydrochloric acid in Dioxane (2.05 ml, 8.19 mmol). The reaction mixture was stirred at room temperature for 2 hours. Volatiles were removed in vacuo and the residue was dissolved in ethyl acetate. The organic phase was extracted with a 1.0M aqueous solution of sodium bicarbonate and the organic phase was collected. The aqueous phase was back-extracted with ethyl acetate. The combined organic phases were dried over sodium sulfate and evaporated down to dryness. The crude material was purified by flash chromatography on silica eluting with a heptane\ethyl acetate gradient to yield the title compound (577 mg, 85%) as a light yellow oil. MS (ESI, m/z): 248.6 (M+H+).
