To a solution of 8-(1,1-dimethylethyl) 3-ethyl 2-{N-[(methyloxy)carbonyl]-L-valyl}-2,8-diazaspiro[4.5]decane-3,8-dicarboxylate (132) (125 mg, 0.27 mmol) in THF/water/MeOH (1.2 mL/0.6 mL/0.6 mL) was added lithium hydroxide monohydrate (22 mg, 0.53 mmol) and the reaction stirred at room temperature for 1.5 h. The reaction was treated with 1N HCl (0.5 mL) and partitioned between EtOAc and 0.1 N HCl (10 mL each) and the aqueous layer extracted with EtOAc (10 mL). The organic layers were combined and dried (MgSO4) and concentrated in vacuo to afford the title compound as a white solid (107 mg, 91% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 12.29-12.54 (m, 1H) 7.08-7.44 (m, 1H) 4.47 (t, J=5.4 Hz, 1H) 4.13-4.30 (m, 1H) 3.86-4.13 (m, 3H) 3.45-3.58 (m, 3H) 3.16-3.27 (m, 2H) 2.64 (br. s., 1 H) 2.15-2.31 (m, 1H) 1.81-1.95 (m, 1H) 1.43-1.67 (m, 3H) 1.29-1.43 (m, 11H) 0.69-1.03 (m, 6H).
