Procedure

A solution of 97.0 mg (0.170 mmol) of 4-cyano-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole-2-carboxylic acid [2-(4,4-dimethyl-cyclohex-1-enyl)-4-(2-methylsulfamoyl-ethyl)-phenyl]-amide (as prepared in the previous step) in CH2Cl2 (30 mL) was treated with MeOH (1 mL) and TFA (10 mL) at RT for 1 h. MeOH (10 mL) was added and the solvents were removed in vacuo. The residue was purified by RP-HPLC (C18) with 40-100% CH3CN in 0.1% TFA/H2O over 30 min to afford 19.8 mg (26%) of the title compound as a white solid: 1H-NMR (CD3CN; 400 MHz): δ 9.41 (s, 1H), 8.24 (d, 1H, J=8.0 Hz), 7.91 (s, 1H), 7.22 (dd, 1H, J=8.0, 2.0 Hz), 5.79-5.74 (m, 1H), 5.08-5.00 (m, 1H), 3.34-3.27 (m, 2H), 3.06-2.99 (m, 2H), 2.70 (d, 3H, J=5.2 Hz), 2.35-2.28 (m, 2H), 2.10-2.05 (m, 2H), 1.59 (t, 2H, J=6.4 Hz), 1.10 (s, 6H). Mass spectrum (ESI, m/z): Calcd. for C22H27N5O3S, 442.2 (M+H). found 442.1.
