Procedure
To a solution of methyl 2-hydroxy-3-methyl-3-phenylbutanoate (0.50 g, 2.4 mmol, from Reference Example 37) in diethyl ether (11 mL) is added silver (I) oxide (4.3 g) and iodomethane (8.7 mL). The reaction mixture is stirred in a 40° C. oil bath under nitrogen atmosphere for 26 hours. The reaction mixture is combined with that from a previous run conducted under the same conditions and filtered through a plug of diatomaceous earth. The filtrate is concentrated under reduced pressure and then purified by flash chromatography (silica gel, hexanes/ethyl acetate) to furnish 0.52 g of a clear, colorless liquid (68% combined yield). MS (ES+): (M+H)=222.9
