実験手順

A solution of (S)-3-cyclohexyl-2-[4-(2-methoxy-phenoxy)-2-oxo-2,5-dihydro-pyrrol-1-yl)-propionic acid (375 mg, 1.04 mmol) in dichloromethane (15 mL) was treated with 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide (164 mg, 1.06 mmol) and 1-hydroxybenzotriazole (150 mg, 2.00 mmol). The reaction mixture was stirred at 25° C. for 2 h followed by the addition of 1-(3-amino-pyrazol-1-yl)-2-methyl-propan-2-ol (prepared in U.S. Pat. Appl. US2008021032 Example 80, 178 mg, 1.15 mmol). The reaction mixture was then 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, a 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 100% ethyl acetate/hexanes) to afford (S)-3-cyclohexyl-N-[1-(2-hydroxy-2-methyl-propyl)-1H-pyrazol-3-yl]-2-[4-(2-methoxy-phenoxy)-2-oxo-2,5-dihydro-pyrrol-1-yl)-propionamide (200 mg, 40%) as an off-white solid: LR-ES-MS m/z calculated for C27H36N4O5 [M]+ 496, observed [M+H]+ 497; 1H NMR (300 MHz, DMSO-d6) δ ppm 0.69-1.35 (m, 6H) 1.05 (br. s., 3H) 1.06 (br. s, 3H) 1.49-1.89 (m, 7H) 3.81 (s, 3H) 3.89 (s, 2H) 4.10 (d, J=18.4 Hz, 1H) 4.52 (d, J=18.4 Hz, 1H) 4.68 (s, 1H) 4.71 (s, 1H) 4.82-4.96 (m, 1H) 6.44 (d, J=2.2 Hz, 1H) 6.94-7.07 (m, 1H) 7.18-7.24 (m, 1H) 7.30 (m, 2H) 7.54 (d, J=2.2 Hz, 1H) 10.77 (s, 1H).
