実験手順

Sodium bicarbonate (17.36 g, 207 mmol) was added to an ambient temperature solution of 2-{[(benzyloxy)carbonyl]amino}-3-(4-bromophenyl)propanoic acid (7.79 g, 20.7 mmol), 1-amino-4,4-dimethylhexan-2-ol (3 g, 20.7 mmol), 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (7.92 g, 41.4 mmol) and 1-hydroxybenzotriazole (5.58 g, 41.4 mmol) in methylene chloride (150 mL). After stirring at ambient temperature overnight, the reaction mixture was quenched with water and extracted with methylene chloride. The combined organic extracts were dried (magnesium sulfate) and concentrated in vacuo. Chromatography over silica eluting with 0-80% ethyl acetate/hexane afforded benzyl {1-(4-bromobenzyl)-2-[(2-hydroxy-4,4-dimethylhexyl)amino]-2-oxoethyl}carbamate.
