Procedure

[7-(3,5-Dimethoxyphenyl)-7-methyl-1-octynyl]trimethylsilane (1 equiv.) was dissolved in anhydrous methanol (0.8 M), anhydrous potassium carbonate (0.2 equiv.) was added and the heterogeneous mixture was stirred at room temperature, under argon, for 24 hours. The reaction mixture was diluted with water and extracted with diethyl ether. The ether extract was dried, concentrated by rotary evaporation and the residue was purified by chromatography on silica gel (5% diethyl ether-petroleum ether) to give the title compound in 76% yield.
