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 (77 mg, 0.16 mmol) (as prepared in Example 14, step (b)), NEt3 (24 μL, 0.16 mmol), acrylonitrile (12 μL, 0.18 mmol), 0.1 mL MeOH and 1.0 mL of 1,2-dichloroethane and stirred for 1 h at 80° C. The reaction was concentrated and the title compound was purified by RP-HPLC (C18), eluting with 30-50% CH3CN in 0.1% TFA/H2O over 12 min to give 83 mg (95%) of a white solid. 1H-NMR (400 MHz, CD3OD): δ 8.18 (d, 1H), 8.06 (m, 1H), 7.22 (dd, 1H), 7.12 (d, 1H), 5.82 (m, 1H), 3.76 (m, 2H), 3.60 (m, 2H), 3.28 (t, 2H), 3.12 (t, 2H), 2.92 (m, 1H), 2.30 (m, 4H), 2.18-1.98 (m, 4H), 1.92-1.74 (m, 4H). Mass spectrum (ESI, m/z): Calcd. for C25H28N6O, 429.2 (M+H), found 429.2.
