Procedure

A solution of 221 mg (0.367 mmol) of 4-cyano-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole-2-carboxylic acid {2-cyclohex-1-enyl-4-[2-(morpholine-4-sulfonyl)-ethyl]-phenyl}-amide (as prepared in the previous step) in CH2Cl2 (20 mL) was treated with EtOH (3 drops) and TFA (1.8 mL) and stirred at RT for 2 h. Solvents were evaporated in vacuo, and the resulting residue was chromatographed on a 25-g Varian MegaBond Elut SPE column with 50-70% EtOAc-hexane to afford 6.6 mg (4%) of the title compound as a white solid: 1H-NMR (CD3OD; 400 MHz): δ 8.15 (d, 1H, J=8.0 Hz), 7.96 (s, 1H), 7.20 (dd, 1H, J=8.0, 2.0 Hz), 7.12 (s, 1H, J=2.0 Hz), 5.83-5.78 (m, 1H), 3.72-3.66 (m, 4H), 3.48-3.46 (m, 1H), 3.26-3.20 (m, 4H), 3.14-3.11 (m, 1H), 3.10-3.03 (m, 2H), 2.32-2.23 (m, 4H), 1.90-1.73 (m, 4H). Mass spectrum (ESI, m/z): Calcd. for C23H27N5O4S, 470.2 (M+H). found 469.9.
