Procedure

Lithium hydroxide monohydrate (104 mg, 2.48 mmol) was added in one portion to a solution of methyl trans-4-{4-[({5-[(2,4,5-trifluorophenyl)amino]-1,3,4-oxadiazol-2-yl}carbonyl)-amino]phenoxy}cyclohexanecarboxylate (Example 449, 125 mg, 0.25 mmol) in a mixture of THF (2 mL), H2O (2 mL) and MeOH (4 mL) and the reaction mixture was stirred at 35° C. for 1 h. The reaction mixture was concentrated in vacuo and citric acid (15 mL) was added. The resulting mixture was filtered, washed with H2O and the white solid was then triturated with hot MeOH and filtered to give the title compound (93 mg, 79%) as a solid. The compound may be recrystallised from a 4:6:1 mixture of EtOH:MeOH:H2O; melting point 263-265° C.
