Reaction Steps

Lithium hydroxide (57 mg, 1.37 mmol) was added to a solution of N-Acetyl-tyrosinyl-valinyl-(4-phenoxy)proline methyl ester (360 mg, 0.685 mmol) dissolved in 8 ml of tetrahydrofuran/water (1:1) and stirred at room temperature for 1 hour. The mixture was acidified with 10% hydrochloric acid giving a white precipitate that was collected to give 175 mg of the title compound.
