Participants

Reaction Steps

Using General Procedure I; a solution of methyl {4-[4-(1-benzyloxycyclopropyl)-3-ethyl-phenylethynyl]-phenyl}-acetate (Compound 92, 130.0 mg, 0.31 mmol) in ethanol (3 mL) and tetrahydrofuran (3 mL) was treated with NaOH (120.0 mg, 3.0 mmols, 3.0 mL of a 1N aqueous solution) and stirred overnight at room temperature. Work-up and purification by HPLC (Partisil 10-pac, 10% H2O/CH3CN) afforded the title compound.
