実験手順

1.0 M of Lithium hexamethyldisilazide in tetrahydrofuran (2.2 mL, 2.2 mmol) was added to a solution of methylcyclohexylacetate (0.30 g, 1.9 mmol) (Aldrich, Cat. #209600) in tetrahydrofuran (7.0 mL) at −78° C. The mixture was stirred at −78° C. for 1 h., then methyl iodide (0.14 mL, 2.3 mmol) was added. The mixture was allowed to warm slowly to r.t., and stirred at r.t. overnight. The mixture was diluted with water, and extracted with ethyl acetate (3×10 mL). The combined organic layers were dried over MgSO4, filtered and concentrated under reduced pressure. The residue was purified by flash chromatography on a silica gel column with ethyl acetate in hexanes (0-10%) to afford the desired product (0.30 g, 92%).
