실험 절차

To a solution of 4-cyano-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole-2-carboxylic acid (4-bromo-2-cyclohex-1-enyl-phenyl)-amide (as prepared in the previous step, 1.20 g, 2.39 mmol) in 10 mL of DCM (CH2Cl2) was added 0.30 mL of EtOH followed by 5.0 mL of TFA. After stirring at RT for 3 h, the mixture was treated with 20 mL of n-propanol and concentrated in vacuo. The residue was triturated with DCM to afford 853 mg (96%) of the title compound as a white solid. 1H-NMR (DMSO-d6; 400 MHz): δ 9.80 (s, 1H), 8.30 (s, 1H), 7.94 (d, 1H, J=8.6 Hz), 7.50 (dd, 1H, J=8.6, 2.3 Hz), 7.39 (d, 1H, J=2.3 Hz), 5.80 (m, 1H), 2.12-2.25 (m, 4H), 1.61-1.77 (m, 4H). Mass spectrum (ESI, m/z): Calcd. for C17H15BrN4O, 371.0 (M+H). found 371.0.
