Participants

Reaction Steps

A solution 4,4-dimethyl-8-(2-trimethylsilanyl-ethoxymethoxy)-6-trimethylsilanylethynyl-3,4-dihydro-2H-naphthalen-1-one (Intermediate 72, 1.58 g, 3.79 mmol) in methanol (20 mL) was treated with potassium carbonate (0.43 g, 3.11 mmol) and the resulting reaction mixture was stirred at ambient temperature overnight. The solvent was evaporated in vacuo, the residue was diluted with water and extracted with ethyl acetate. The organic phase was washed with brine, dried over anhydrous magnesium sulfate, filtered and evaporated in vacuo to afford the title compound (1.28 g, 98%).
