Versuchsvorschrift

A solution of (S)-2-[4-(2-chloro-phenoxy)-2-oxo-2,5-dihydro-pyrrol-1-yl]-3-(4-chlorophenyl)-propionic acid [1-((R)-2,2-dimethyl-[1,3]dioxolan-4-yl-methyl)-1H-pyrazol-3-yl]-amide (prepared as in Example 188, 0.151 g, 0.259 mmol) in tetrahydrofuran (3 mL) was treated with 2N aqueous hydrochloric acid solution (3 mL). The reaction mixture was stirred at 25° C. for 3 h. The reaction mixture was diluted with ethyl acetate, washed with water, saturated sodium bicarbonate solution, a saturated sodium chloride solution and dried over magnesium sulfate. The organic layer was concentrated to afford, (S)-2-[4-(2-chloro-phenoxy)-2-oxo-2,5-dihydro-pyrrol-1-yl]-3-(4-chlorophenyl)-N-[1-((R)-2,3-dihydroxy-propyl)-1H-pyrazol-3-yl]-propionamide (0.110 g, 80%) as a white powder: HR-ES-MS m/z calculated for C25H24Cl2N4O5 [M+H]+ 531.1196, observed 531.1197; 1H NMR (300 MHz, DMSO-d6); 1H NMR (300 MHz, DMSO-d6) δ ppm 3.19-3.30 (m, 4H), 3.74 (br. s., 1H), 3.80-3.91 (m, 1H), 4.07 (dd, J=13.6, 3.6 Hz, 1H), 4.25 (d, J=18.2 Hz, 1H), 4.39 (d, J=18.2 Hz, 1H), 4.65-4.71 (m, 1H), 4.72 (s, 1H), 4.93 (d, J=5.1 Hz, 1H), 5.18 (t, J=7.5 Hz, 1H), 6.43 (d, J=1.5 Hz, 1H), 7.18-7.30 (m, 2H), 7.30-7.47 (m, 5H), 7.53 (d, J=1.5 Hz, 1H), 7.62 (d, J=7.8 Hz, 1H), 10.76 (s, 1H).
