Procedure

Using General Procedure E; 2-methyl-4-trimethylsilanylethynyl-1-trimethylsilananyloxymethyl-benzene (Intermediate 135, 380.0 mg, 1.30 mmols) in methanol (10 mL) was treated with potassium carbonate (180.0 mg, 1.3 mmol) and stirred overnight at ambient temperature. The crude alkyne was purified by column chromatography (5-20% EtOAc-hexanes) to give 100.0 mg (34%) of the title compound.
