Reaction Steps

Using General Procedure I; a solution of ethyl 4-[4-(1-isopropoxycyclopropyl)-3-ethyl-phenylethynyl]-benzoate (Compound 95, 110.0 mg, 0.29 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 isolation by HPLC (partisil 10-pac, 10% H2O/CH3CN) afforded the title compound as a colorless solid.
