Reaction Steps

The title compound was prepared by the procedure of Example 11, step (g) using 4-cyano-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole-2-carboxylic acid (3-cyclohex-1-enyl-4′-methanesulfonylamino-biphenyl-4-yl)-amide (as prepared in the previous step, 29.5 mg, 0.0498 mmol). Silica gel chromatography (5-10% EtOAc/DCM) afforded the title compound (10.1 mg, 44%) as a white solid. 1H-NMR (CD3OD; 400 MHz): δ 8.29 (d, 1H, J=8.6 Hz), 8.01 (s, 1H), 7.60 (d, 2H, J=8.6 Hz), 7.53 (dd, 1H, J=8.4, 2.0 Hz), 7.42 (d, 1H, J=2.0 Hz), 7.33 (d, 2H, J=8.6 Hz), 5.89 (m, 1H), 2.98 (s, 3H), 2.23-2.38 (m, 4H), 1.77-1.93 (m, 4H). Mass spectrum (ESI, m/z): Calcd. for C24H23N5O3S, 462.2 (M+H), found 461.9.
