実験手順

[2′-[(cyclopropanecarbonyl-ethyl-amino)-methyl]-4′-(6-ethoxy-pyridin-3-yl)-6-methoxy-biphenyl-3-yl]-acetic acid ethyl ester (32.7 g, 63.3 mmol) in tetrahydrofuran (150 mL) and water (75 mL) was treated with lithium hydroxide (8.0 g, 190.6 mmol) and the reaction was stirred at room temperature overnight. When the reaction was complete by analytical LCMS, the mixture was acidified with 1N aqueous hydrochloric acid to pH 3 and extracted 2 times with dichloromethane. The combined organic layers were dried over magnesium sulfate and concentrated to afford the title compound as an off-white foam.
