Versuchsvorschrift

A solution of (S)-2-[4-(2-methoxy-phenoxy)-2-oxo-2,5-dihydro-pyrrol-1-yl]-3-(tetrahydro-furan-2-yl)-propionic acid (90 mg, 0.26 mmol) in dichloromethane (10 mL) was treated with 1-(3-amino-pyrazol-1-yl)-2-methyl-propan-2-ol (prepared in U.S. Pat. Appl. US2008021032 Example 80, 45 mg, 0.29 mmol), Benzotriazol-1-yl-oxy-tris(dimethylamino)phosphonium hexafluorophosphate (140 mg, 0.31 mmol) and N,N-diisopropylethylamine (100 mg, 0.78 mmol). The reaction mixture was stirred for 18 h at 25° C., under nitrogen. The reaction mixture was diluted with dichloromethane, washed with 2N aqueous hydrochloric acid, saturated sodium bicarbonate solution, saturated sodium chloride solution and dried over magnesium sulfate. The organic layer was concentrated, and the crude product was purified by ISCO flash chromatography (Teledyne Isco RediSep Flash Column 12 g; 0% to 10% methanol/dichloromethane) to afford (S)-N-[1-(2-hydroxy-2-methyl-propyl)-1H-pyrazol-3-yl]-2-[4-(2-methoxy-phenoxy)-2-oxo-2,5-dihydro-pyrrol-1-yl]-3-(tetrahydro-furan-2-yl)-propionamide (45 mg, 36%) as a yellow solid: LR-ES-MS m/z calculated for C25H32N4O6 [M]+ 484, observed [M+H]+ 485; 1H NMR (300 MHz, DMSO-d6) δ ppm 1.05 (br. s., 3H) 1.06 (br. s., 3H) 1.35-2.11 (m, 6H) 3.54-3.79 (m, 3H) 3.81 (s, 3H) 3.89 (s, 2H) 4.18, 4.22 (2×d, J=18.0, 1H) 4.45 (d, J=18.0 Hz, 1H) 4.68 (s, 1H) 4.70 (s, 1H) 4.77-4.91 (m, 1H) 6.40-6.48 (m, 1H) 6.95-7.06 (m, 1H) 7.18-7.25 (m, 1H) 7.25-7.36 (m, 2H) 7.51-7.56 (m, 1H) 10.70, 10.73 (2×s, 1H).
