The procedure of Example 4 was followed using 4-cyano-1H-imidazole-2-carboxylic acid [4-(1-amino-1-methyl-ethyl)-2-cyclohex-1-enyl-phenyl]-amide acetic acid salt (as prepared in Example 3, step (b), 28.0 mg, 0.0684 mmol), oxalyl chloride (51 μL, 0.10 mmol, 2.0 M in DCM) and DIEA (36 μL, 0.21 mmol). Flash chromatography on silica gel (1-2% MeOH/DCM) afforded 9.2 mg (34%) of the title compound as a white solid. 1H-NMR (CD3OD; 400 MHz): δ 8.14 (d, 1H, J=8.4 Hz), 7.99 (s, 1H), 7.31 (dd, 1H, J=8.4, 2.3 Hz), 7.20 (d, 1H, J=2.3 Hz), 5.81 (m, 1H), 2.22-2.31 (m, 4H), 1.74-1.89 (m, 4H), 1.71 (s, 6H). Mass spectrum (ESI, m/z): Calcd. for C22H24N6O3, 421.2 (M+H). found 421.0.
