Methyl iodide → (3,5-Di-tert-butyl-4-methoxy-phenylethynyl)-trimethyl-silane

Participants

Reaction Steps

A solution 2,6-di-tert-butyl-4-trimethylsilanylethynyl-phenol (Intermediate 167, 0.302 g, 1 mmol) in acetone (5 mL) was treated with potassium carbonate (0.138 g, 1 mmol) and methyl iodide (0.142 g, 1 mmol) and stirred overnight at room temperature. The volatiles were distilled off in vacuo and the residue was purified by flash column chromatography on silica gel (230-400 mesh) using ethyl acetate as the eluent to afford the title compound as a white solid (0.28 g, 90%).
