Procedure
To a solution of (trans-4-{4-[({5-[(2-fluorophenyl)amino]-1,3,4-oxadiazol-2-yl}carbonyl)amino]phenyl}cyclohexyl)acetic acid (Example 112, 300 mg, 0.68 mmol) in DMF (3 mL) was added HATU (286 mg, 0.75 mmol), diisopropylethylamine (0.14 mL, 0.75 mmol) followed by methyl isonipecotate (0.15 mL, 0.75 mmol). The reaction mixture was allowed to stir at ambient temperature overnight. The DMF was evaporated and the residue re-dissolved in DMSO/MeCN/H2O (7:2:1); a suspension formed which was filtered, washed with ether (2×10 mL) and dried to leave the title compound (137 mg). The filtrate was purified on an acidic reverse phase HPLC system eluting 5-95% MeCN 0.2% TFA, isolated 112 mg of the title compound (249 mg, 65%) as a solid; 1H NMR δ 1.07-1.16 (m, 2H), 1.36-1.53 (m, 4H), 1.75-1.88 (m, 7H), 2.24 (d, 2H), 2.41-2.47 (m, 1H), 2.59-2.65 (m, 2H), 3.11 (t, 1H), 3.62 (s, 3H), 3.85 (d, 1H), 4.26 (d, 1H), 7.14-7.34 (m, 5H), 7.68 (d, 2H), 8.04 (t, 1H), 10.75 (s, 1H), 10.93 (s, 1H); MS m/e MH+ 564.
