Procedure

To (2S,3S)-2-amino-3-hydroxy-N-((S)-3-(4-methoxyphenyl)-1-(((S)-1-((R)-2-methyloxiran-2-yl)-1-oxo-3-phenylpropan-2-yl)amino)-1-oxopropan-2-yl)butanamide TFA salt (0.207 mmol assumed) was added 2-morpholinoacetic acid (48.0 mg, 0.331 mmol), HATU (0.126 g, 0.331 mmol), and DMF (1 mL). The mixture was cooled to 0° C. and DIEA (0.177 mL, 0.104 mmol) was added. The reaction mixture was stirred at ambient temperature for 30 min then quenched with sodium bicarbonate (sat.), extracted with ethyl acetate (2×), dried with sodium sulfate, filtered, and concentrated. Purification by column chromatography (3:1 DCM/ethyl acetate+0-10% methanol) provided (25,35)-3-hydroxy-N-((S)-3-(4-methoxyphenyl)-1-(((S)-1-((R)-2-methyloxiran-2-yl)-1-oxo-3-phenylpropan-2-yl)amino)-1-oxopropan-2-yl)-2-(2-morpholinoacetamido)butanamide (80 mg, 63%) as a colorless solid.
