실험 절차

A solution of (S)-2-[4-(3-ethoxy-2,6-difluoro-phenoxy)-2-oxo-2,5-dihydro-pyrrol-1-yl]-4-methyl-pentanoic acid [1-((R)-2,2-dimethyl-[1,3]dioxolan-4-yl-methyl)-1H-pyrazol-3-yl]-amide (prepared in Example 116, 1.140 g, 2.08 mmol) in tetrahydrofuran (100 mL) was treated with 2N aqueous hydrochloric acid (150 mL). The reaction mixture was stirred for 2.5 h at room temperature. The reaction mixture was diluted with ethyl acetate, washed with saturated sodium bicarbonate, a saturated sodium chloride solution and dried over magnesium sulfate. The mixture was filtered and evaporated and the residue purified by ISCO flash chromatography (Teledyne Isco RediSep Flash Column 40 g, 30% to 100% (9:1 dichloromethane:methanol)/hexanes) which afforded (S)-2-[4-(3-ethoxy-2,6-difluoro-phenoxy)-2-oxo-2,5-dihydro-pyrrol-1-yl]-4-methyl-pentanoic acid [1-((R)-2,3-dihydroxy-propyl)-1H-pyrazol-3-yl]-amide (0.780 g, 74%) as a white solid: HR-ES-MS m/z calculated for C24H30F2N4O6, [M+H]+ 509.2206 observed 509.2206; 1H NMR (300 MHz, DMSO-d6) δ ppm 0.90 (d, J=6.6 Hz, 3H), 0.93 (d, J=6.6 Hz, 3H), 1.35 (t, J=6.8 Hz, 3H), 1.38-1.50 (m, 1H), 1.50-1.67 (m, 1H), 1.68-1.85 (m, 1H), 3.20-3.33 (m, 2H), 3.71-3.94 (m, 2H), 4.04-4.20 (m, 3H), 4.26 (d, J=18.7 Hz, 1H), 4.63 (d, J=18.7 Hz, 1H), 4.71 (t, J=5.3 Hz, 1H), 4.87 (dd, J=10.3, 4.5 Hz, 1H), 4.94 (d, J=4.8 Hz, 1H), 5.05 (s, 1H), 6.41 (s, 1H), 7.09-7.35 (m, 2H), 7.53 (s, 1H), 10.79 (s, 1H).
