Procedure

A flask was charged with 4-cyano-1H-imidazole-2-carboxylic acid (2-cyclohex-1-enyl-4-piperidin-4-yl-phenyl)-amide TFA salt (25 mg, 0.05 mmol) (as prepared in Example 14, step (b)), pyridin-2-yl-acetic acid hydrochloride (10 mg, 0.06 mmol), EDCI (12 mg, 0.06 mmol), HOBt (8.0 mg, 0.06 mmol), DIEA (36 ,uL, 0.20 mmol) and 0.2 mL DMF and stirred at 25° C. for 10 h. The reaction was diluted with 2 mL of H2O and the title compound was purified by RP-HPLC (C18), eluting with 30-50% CH3CN in 0.1% TFA/H2O over 9 min to give 22 mg (70%) of a white solid. 1H-NMR (400 MHz, CD3OD): δ 8.82 (d, 1H), 8.52 (t, 1H), 8.14 (d, 1H), 8.04 (s, 1H), 7.96 (m, 3H), 7.20 (dd, 1H), 7.10 (d, 1H), 5.82 (m, 1H), 4.68 (m, 1H), 4.32 (m, 2H), 4.18 (m, 1H), 3.40 (m, 1H), 2.88 (m, 2H), 2.30 (m, 4H), 2.06-1.60 (m, 8H). Mass spectrum (ESI, m/z): Calcd. for C29H30N6O2, 495.2.2 (M+H), found 495.2.
