Procedure
HATU (502 mg, 1.3 mmol) and DIPEA (1.35 mL) were added to a solution of (S)-3-hydroxy-2-(2-morpholinoacetamido)propanoic acid (225 mg, 0.97 mmol) and (S)-2-amino-N-((S)-3-(cyclohex-1-en-1-yl)-1-((R)-2-methyloxiran-2-yl)-1-oxopropan-2-yl)-3-(4-(methylsulfonyl)phenyl)propanamide (0.88 mmol) in DMF (20 mL) at 0° C. with stirring. The reaction mixture was allowed to warm to ambient temperature and stirred for 3 h. EtOAc (100 mL) and water (100 mL) was added and the two layers were separated. The aqueous phase was extracted with EtOAc (50 mL×3). The combined organic phases were washed with brine (200 mL×3), dried over anhydrous sodium sulfate and concentrated. The residue was purified by flash column chromatography on silica gel (CH2Cl2/EtOAc/MeOH=20:10:0.2) to afford (S)-N-((S)-3-(cyclohex-1-en-1-yl)-1-((R)-2-methyloxiran-2-yl)-1-oxopropan-2-yl)-2-((S)-3-hydroxy-2-(2-morpholinoacetamido)propanamido)-3-(4-(methylsulfonyl)phenyl)propanamide (200 mg, 35% yield). 1H NMR (300 MHz, DMSO-d6): δ 8.33 (d, J=7.2 Hz, 1H), 8.13 (d, J=8.4 Hz, 1H), 7.78 (d, J=8.1 Hz, 2H), 7.69 (d, J=7.8 Hz, 1H), 7.46 (d, J=7.8 Hz, 2H), 5.40 (m, 1H), 5.05 (m, 1H), 4.45-4.70 (m, 2H), 4.30 (m, 1H), 3.57 (m, 4H), 3.50 (m, 2H), 3.22 (m, 1H), 3.20 (s, 3H), 3.10 (m, 1H), 2.80-3.00 (m, 4H), 2.40 (m, 2H), 2.20 (m, 2H), 1.90-2.10 (m, 4H), 1.50-1.70 (m, 3H), 1.37 (s, 3H), 1.00-1.30 (m, 3H). MS (EI) for C31H44N4O9S, found 649.0 (MH)+.
