Procedure

To a solution of 4-cyano-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole-2-carboxylic acid {2-cyclohex-1-enyl-4-[1-(2-morpholin-4-yl-ethyl)-piperidin-4-yl]-phenyl}-amide (650 mg, 1.05 mmol) (as prepared in the previous step) in 10 mL of DCM was added 0.3 mL of EtOH and 3.0 mL of TFA, and the reaction was allowed to proceed for 2 h at 25° C. The reaction was diluted with 10 mL of EtOH and concentrated. The title compound was purified by RP-HPLC (C18), eluting with 30-50% CH3CN in 0.1% TFA/H2O over 9 min to give 600 mg (80%) of a white solid. 1H-NMR (400 MHz, CD3OD): δ 8.18 (d, 1H), 8.04 (s, 1H), 7.24 (dd, 1H), 7.14 (d, 1H), 5.84 (m, 1H), 3.84 (m, 4H), 3.76 (m, 2H), 3.50 (m, 2H), 3.30-3.10 (m, 4H), 2.92 (m, 5H), 2.30 (m, 4H), 2.20-2.00 (m, 4H), 1.90-1.74 (m, 4H). Mass spectrum (ESI, m/z): Calcd. for C28H36N6O2, 489.2. found 489.2.
