Phenylmethyl 3-[3-cyclohexyl-5-({[2-(ethyloxy)-2-oxoethyl]amino}carbonyl)-6-hydroxy-2,4-dioxo-3,4-dihydro-1(2H)-pyrimidinyl]-1-piperidinecarboxylate (100 mg, 0.18 mmoles) was dissolved in ethanol (3.0 mL) and treated with 6 molar sodium hydroxide (1.5 mL). The mixture was stirred for 2 hours, acidified and extracted with ethyl acetate (×2). The combined extracts were washed with 1 molar hydrochloric acid, dried and evaporated to a foam (80 mg, 84%). 1H NMR (400 MHz, DMSO-d6) δ ppm 13.11 (s, 1 H), 10.17 (s, 1 H), 7.30-7.40 (m, 5 H), 5.10 (s, 2H), 4.57-4.69 (m, 2 H), 4.13 (d, J=5.81 Hz, 2 H), 3.95-4.05 (m, 2 H), 3.64 (s, 1 H), 3.37 (s, 1 H), 2.73 (s, 1 H), 2.36-2.48 (m, 1 H), 2.25 (q, J=11.62 Hz, 2 H), 1.70-1.82 (m, 4 H), 1.62 (d, J=11.37 Hz, 3 H), 1.38-1.50 (m, 1 H), 1.21-1.33 (m, 2 H), 1.06-1.18 (m, 1 H)
