Reaction Steps
(2S,4R)-5-Biphenyl-4-yl-4-t-butoxycarbonylamino-2-hydroxymethyl-2-methyl-pentanoic acid (100 mg, 242 μmol), HOBt (98 mg, 726 μmol), and EDCI (128 μL, 726 μmol) were dissolved in DCM (2 mL). After stirring for 15 minutes, benzyl alcohol (200 μL, 1.9 mmol) and 4-methylmorpholine (106 μL, 967 μmol) were added. The resulting mixture was stirred at room temperature overnight, and then the reaction was quenched with water. The DCM layer was separated, concentrated, purified ((Interchim reverse phase chromatography column), and dried under vacuum. The purified material was combined with MeCN (1 mL, 20 mmol) and 4 M HCl in dioxane (240 μL, 970 μmmol) and stirred at room temperature for 1 hour. The solvent was then removed to yield (2S,4R)-4-amino-5-biphenyl-4-yl-2-hydroxymethyl-2-methyl-pentanoic acid benzyl ester.
