실험 절차

To a solution of 4-cyano-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole-2-carboxylic acid [4-bromo-2-(4,4-dimethyl-cyclohex-1-enyl)-phenyl]-amide (0.95 g, 1.80 mmol) (prepared in the previous step) in 10 mL of DCM was added 0.4 mL of EtOH and 10 mL of TFA and the mixture stirred for 1 h at RT. The mixture was concentrated and triturated with Et2O to give 0.68 g (95%) of a white solid: 1H-NMR (400 MHz, CDCl3): δ 11.23 (br s, 1H), 9.52 (br s, 1H), 8.27 (d, J=8.7 Hz, 1H), 7.72 (s, 1H), 7.41 (dd, J=2.3, 8.7 Hz, 1H), 7.33 (d, J=2.3 Hz, 1H), 5.82 (m, 1H), 2.28 (m, 2H), 2.10 (m, 2H), 1.58 (m, 2H), 1.08 (s, 6H). Mass spectrum (ESI, m/z): Calcd. for C19H19BrN4O, 399.1 (M+H). found 399.0.
