Reaction Steps
Using General Procedure I; a solution of methyl {4-[4-(1-isopropoxycyclopropyl)-3-ethyl-phenylethynyl]-phenyl}-acetate (Compound 96, 156.0 mg, 0.41 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 85.0 mg (57%) of the title compound.
