A solution of lithium hydroxide (101 mg, 2.41 mmol) in H2O (1.5 mL) was added in one portion to a solution of methyl {trans-4-[4-({[5-(pyrimidin-4-ylamino)-1,3,4-oxadiazol-2-yl]-carbonyl}amino)phenyl]cyclohexyl}acetate (Example 416, 105 mg, 0.24 mmol) in a mixture of THF (1.8 mL) and MeOH (3 mL) and the reaction mixture was stirred at 35° C. for 2 h. Citric acid (50 mL) and EtOAc (50 mL) were added and the layers were separated and the aqueous layer was filtered to leave a solid. The solid was washed with water (10 mL) to give the title compound as a yellow brown solid (60 mg, 59%); 1H NMR δ 1.07-1.18 (2H, m), 1.41-1.51 (2H, m), 1.69-1.85 (5H, m), 2.14-2.16 (2H, d), 7.24 (2H, d), 7.71 (2H, d), 7.92 (1H, d), 8.69 (1H, d), 8.87 (1H, s), 11.00 (1H, s), 12.06 (2H, s); MS m/e MH+ 423.
