Procedure

A sample of 2-[benzyl-(biphenyl-4-carbonyl)-amino]-4-[4-(1-ethoxycarbonyl-1-methyl-ethoxy)-phenoxy]-butyric acid ethyl ester (687 mg, 1.10 mmol) was dissolved in 5 mL of dioxane followed by addition of 5.0 N NaOH (2.3 mL, 11.6 mmol). The mixture was magnetically stirred and heated at 60° C. for 7 hours. The reaction mixture was allowed to cool to room temperature followed by addition of 1.0 N HCl (12 mL, 12 mmol) then partitioned by addition of methylene chloride (50 mL). The organic phase was separated, dried over sodium chloride and concentrated under reduced pressure to yield 690 mg (˜100%) of a glassy solid. HPLC RT1=2.24 min; 1H NMR (400 MHz, CDCl3) δ 12.82 (broad s, 2H), 7.70-7.75 (m, 4H), 7.45-7.17 (m, 10H), 6.75-6.48 (m, 4H), 2.24-2.00 (m, 2H), 1.39 (s, 6H); MS (EI) 568.31 (M+H)+.
