실험 절차

To a mixture of 4-bromo-2-(4,4-dimethyl-cyclohex-1-enyl)-phenylamine (as prepared in the previous step, 770 mg, 2.75 mmol), potassium 4-cyano-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole-2-carboxylate (US Pat Applic 2006189623 A1, 840 mg, 2.75 mmol) and PyBroP (1.28 g, 2.75 mmol) in 20 mL of DMF was added DIEA (1.44 mL, 8.25 mmol). The resulting mixture was stirred at RT for 16 h under Ar. Treated with 80 mL of EtOAc, the mixture was washed with H2O (2×20 mL), brine (20 mL) and dried (Na2SO4). Removal of the solvent under reduced pressure followed by flash chromatography of the residue on silica gel (5-10% EtOAc/hexane) gave 1.28 g (88%) of the title compound as a white solid. Mass spectrum (ESI, m/z): Calcd. for C25H33BrN4O2Si, 529.2 (M+H), found 528.9.
