Procedure
(2-Adamantyl) 9-(2-methoxy-2-oxoethyl)-3-azaspiro[5.5]undecane-3-carboxylate (30 mg, 74 μmol) was dissolved in THF (0.25 mL), water (0.25 mL) and MeOH (0.5 mL) and LiOH.H2O (8 mg, 0.19 mmol) was added. The mixture was stirred at rt for 2 d and TFA (10 mL, 0.14 mmol) was added. The solution was submitted directly to prep HPLC to afford 2-(34(2-adamantyl)oxycarbonyl)-3-azaspiro[5.5]undecan-9-yl)acetic acid (10.5 mg, 36%). LC-MS Method 1 tR=2.17 min, m/z=390; 1H NMR (CDCl3) δ=1.0-2.05 (27H), 2.27 (d, 2H), 3.44 (m, 4H), 4.83 (s, 1H).
