Procedure

A solution of 8-hydroxy-4,4-dimethyl-6-trimethylsilanylethynyl-3,4-dihydro-2H-naphthalen-1-one (Intermediate 66, 0.32 g, 1.12 mmol) in acetone (20 mL) was treated with potassium carbonate (0.773 g, 5.6 mmol) and 2-iodopropane (2 g, 11.76 mmol) and the resulting reaction mixture was refluxed for 3 days. It was cooled to ambient temperature, the solids were filtered off and the filtrate was evaporated in vacuo to an oil that was subjected to flash column chromatography over silica gel (230–400 mesh) using 2–6% ethyl acetate in hexane as the eluent to afford the title product as (0.055 g, 15%).
