실험 절차

Ammonium acetate (48 g, 620 mmol) was added to an ambient temperature solution of benzyl {1-(4-bromobenzyl)-2-[(4,4-dimethyl-2-oxohexyl)amino]-2-oxoethyl}carbamate (6.23 g, 12.4 mmol) in xylene (124 mL). After stirring at 150° C. for 2 h, the reaction mixture was quenched with saturated aqueous sodium bicarbonate and extracted with methylene chloride. The combined organic extracts were dried (magnesium sulfate) and concentrated in vacuo to afford benzyl {2-(4-bromophenyl)-1-[4-(2,2-dimethylbutyl)-1H-imidazol-2-yl]ethyl}carbamate which was used in the subsequent step without further purification.
