Procedure

Using General Procedure I; a solution of methyl {4-[4-(1-methoxycyclopropyl)-phenylethynyl]-phenyl}-acetate (Compound 68, 100.0 mg, 0.31 mmol) in ethanol (3 mL) and tetrahydrofuran (3 mL) was treated with NaOH (160.0 mg, 4.0 mmols, 2.0 mL of a 2N aqueous solution) and stirred overnight at room temperature. Work-up afforded 80.0 mg (84%) of the title compound as an orange solid.
