The title compound was prepared by the procedure of Example 15, step (c) using 4-cyano-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole-2-carboxylic acid (4-acetyl-2-cyclohex-1-enyl-phenyl)-amide (as prepared in the previous step, 40.0 mg, 0.0862 mmol). Silica gel chromatography (10% EtOAc/DCM) afforded the title compound (26.2 mg, 91%) as a white solid. 1H-NMR (CDCl3; 400 MHz): δ 11.59 (s, 1H), 9.79 (s, 1H), 8.50 (d, 1H, J=8.6 Hz), 7.92 (dd, 1H, J=8.6, 2.0 Hz), 7.82 (d, 1H, J=2.0 Hz), 7.78 (s, 1H), 5.92 (m, 1H), 2.62 (s, 3H), 2.23-2.39 (m, 4H), 1.77-1.94 (m, 4H). Mass spectrum (ESI, m/z): Calcd. for C19H18N4O2, 335.1 (M+H), found 335.1.
