Reaction Steps

A flask was charged with 4-cyano-1H-imidazole-2-carboxylic acid (2-cyclohex-1-enyl-4-piperidin-4-yl-phenyl)-amide TFA salt (51 mg, 0.10 mmol) (as prepared in Example 14, step (b)), NEt3 (22 μL, 0.15 mmol), trimethylsilyl isocyanate (16 μL, 0.11 mmol) and 1.0 mL of DCM and stirred for 10 h at 25° C. The solvent was evaporated and the title compound was purified by RP-HPLC (C18), eluting with 35-60% CH3CN in 0.1% TFA/H2O over 11 min to give 30 mg (70%) of a white solid. 1H-NMR (400 MHz, DMSO-d6): δ 14.28 (br s, 1H), 9.76 (s, 1H), 8.34 (s, 1H), 7.84 (d, 1H), 7.18 (dd, 1H), 7.08 (d, 1H), 6.00 (br s, 2H), 5.72 (m, 1H), 4.18 (m, 2H), 2.80-2.60 (m, 3H), 2.24-2.10 (m, 4H), 1.80-1.60 (m, 6H), 1.50 (m, 2H). Mass spectrum (ESI, m/z): Calcd. for C23H26N6O, 419.2 (M+H). found 419.0.
