Potassium Carbonate → HCID 59692072, compound

Participants

Reaction Steps

A solution of 6-trimethylsilanylethynyl-2,2,4,4-tetramethyl chroman (Compound 43, 1.78 g, 5.4 mmol) in methanol (20 mL) was treated with potassium carbonate (0.745 g, 5.4 mmol) and the resulting reaction mixture was stirred at ambient temperature for 3 h. The reaction mixture was filtered, the filtrate was evaporated in vacuo and the residue was subjected to flash column chromatography over silica gel (230-400 mesh) using 2-5% ethyl acetate in hexane as the eluent to afford the title compound (1.1 g, 85%).
