Reaction Steps
Using General Procedure E; [4-(1-benzyloxycyclopropyl)-3-methyl-phenylethynyl]-trimethylsilane (Intermediate 75, 300.0 mg, 0.95 mmols) in methanol (6 mL) was treated with potassium carbonate (120.0 mg, 0.87 mmol) and stirred overnight at ambient temperature. The crude alkyne (185 mg, 79%) was used directly in the next reaction.
