실험 절차

To a solution of 4-cyano-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole-2-carboxylic acid [2-cyclohex-1-enyl-4-(1-methoxy-piperidin-4-yl)-phenyl]-amide (as prepared in previous step, 31 mg, 0.020 mmol) in DCM (0.5 mL) and EtOH (11 μL) was added TFA (0.1 mL). The resulting solution was stirred at RT for 6 h. The reaction mixture was concentrated in vacuo and the resulting residue was dried for 1 h, suspended in ether (10 mL) and sonicated for 5 min. The solid formed was collected by suction filtration to obtain the title compound (17.3 mg, 58%). 1H-NMR (DMSO; 400 MHz): δ 9.70 (s, 1H), 8.30 (s, 1H), 7.83 (d, 1H, J=8.4 Hz), 7.14 (d, 1H, J=8.4 Hz), 7.05 (s, 1H), 5.71 (br s, 1H), 3.30-3.55 (m, 5H), 2.41-2.62 (m, 2H), 2.12-2.19 (m, 4H), 1.60-1.85 (m, 8H). Mass spectrum (ESI, m/z): Calcd. for C23H27N5O2, 406.2 (M+H). found 406.1.
