実験手順
To (S)-2-((S)-2-aminopropanamido)-3-(4-methoxyphenyl)-N-((S)-1-((R)-2-methyloxiran-2-yl)-1-oxo-3-phenylpropan-2-yl)propanamide (0.412 mmol assumed) was added a mixture of (R)-tetrahydrofuran-2-carboxylic acid (57 mg, 0.494 mmol), HATU (187 mg, 0.494 mmol), and DMF (3 mL). The mixture was cooled to 0° C. and DIEA (0.352 mL, 2.06 mmol) was added. The reaction mixture was stirred at ambient temperature for 15 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 (R)-N-((S)-1-(((S)-3-(4-methoxyphenyl)-1-(((S)-1-((R)-2-methyloxiran-2-yl)-1-oxo-3-phenylpropan-2-yl)amino)-1-oxopropan-2-yl)amino)-1-oxopropan-2-yl)tetrahydrofuran-2-carboxamide (130 mg, 57%) as a colorless amorphous solid. 1H NMR (400 MHz, DMSO-d6): δ 8.46 (d, J=7.6 Hz, 1H), 7.93 (d, J=8.0 Hz, 1H), 7.54 (d, J=8.0 Hz, 1H), 7.31-7.20 (m, 5H), 7.08 (d, J=8.4 Hz, 1H), 6.77 (d, J=8.4 Hz, 1H), 4.59-4.54 (m, 1H), 4.48-4.42 (m, 1H), 4.21-4.16 (m, 2H), 3.80-3.69 (m, 5H), 3.18 (d, J=5.2 Hz, 1H), 2.98 (d, J=6.4 Hz, 1H), 2.95-2.86 (m, 2H), 2.73-2.59 (m, 2H), 2.05-1.99 (m, 1H), 1.80-1.66 (m, 3H), 1.11 (d, J=7.2 Hz, 3H). MS (EI) for C30H37N3O7, found 552.3 (MH+).
