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 (88 mg, 0.18 mmol) (as prepared in Example 14, step (b)), pyridine-2-carbaldehyde (17 μL, 0.21 mmol), NEt3 (30 μL, 0.21 mmol), sodium triacetoxyborohydride (56 mg, 0.25 mmol) and 0.8 mL of 1,2-dichloroethane and stirred for 10 h at 25° C. The solvent was evaporated, and the title compound was purified by RP-HPLC (C18), eluting with 30-50% CH3CN in 0.1% TFA/H2O over 20 min to give 81 mg (78%) of a white solid. 1H-NMR (400 MHz, DMSO-d6): δ 14.25 (br s, 1H), 9.90 (br s, 1H), 9.79 (s, 1H), 8.72 (s, 1H), 8.36 (s, 1H), 7.98 (m, 1H), 7.88 (dd, 1H), 7.58 (d, 1H), 7.52 (m, 1H), 7.20 (m, 1H), 7.12 (d, 1H), 5.76 (m, 1H), 4.56 (s, 2H), 3.40 (m, 2H), 3.18 (m, 2H), 2.88 (m, 1H), 2.20 (m, 4H), 2.00 (m, 4H), 1.72 (m, 4H). Mass spectrum (ESI, m/z): Calcd. for C28H30N6O, 467.2 (M+H). found 467.2.
