Reaction Steps

[2′-[(tert-Butoxycarbonyl-ethyl-amino)-methyl]-4′-(6-ethoxy-pyridin-3-yl)-6-methoxy-biphenyl-3-yl]-acetic acid ethyl ester (1.09 g, 2.0 mmol) in CH2Cl2 (10 mL) was treated with 4N HCl in 1,4-dioxane (6 mL, 24.0 mmol) at room temperature, until complete conversion was seen by analytical LCMS. The mixture was concentrated to give the title compound.
