実験手順

To a stirred solution of (S)-3-cyclohexyl-2-[4-(3-methoxy-phenoxy)-2-oxo-2,5-dihydro-pyrrol-1-yl]-propionic acid (150 mg, 0.4 mmol) in dichloromethane (10 mL) was gradually added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (85 mg, 0.4 mmol) and N,N-diisopropylethylamine (169 mg, 1.2 mmol) at room temperature, under nitrogen. After 15 min, 1-hydroxybenzotriazole (63 mg, 0.4 mmol) and 1-(3-amino-pyrazol-1-yl)-2-methyl-propan-2-ol (prepared in U.S. Pat. Appl. US2008021032 Example 80, 65 mg, 0.4 mmol) were added to the reaction mixture. The reaction mixture was then stirred at 23° C. for 48 h. The reaction mixture was diluted with ethyl acetate and washed with a saturated aqueous ammonium chloride solution followed by a saturated aqueous sodium bicarbonate solution. The organic layer was then washed with a saturated aqueous sodium chloride solution, separated, dried over sodium sulfate and concentrated in vacuo to afford the crude product, which was purified by flash column chromatography (silica gel (100-200 mesh)) which afforded (S)-3-cyclohexyl-N-[1-(2-hydroxy-2-methyl-propyl)-1H-pyrazol-3-yl]-2-[4-(3-methoxy-phenoxy)-2-oxo-2,5-dihydro-pyrrol-1-yl]-propionamide (0.030 g, 14%) as a light yellow sticky liquid: 1H NMR (400 MHz, CDCl3) δ ppm 0.84-1.09 (m, 2H), 1.17 (s, 6H), 1.19-1.35 (m, 3H), 1.53-1.97 (m, 8H), 2.80 (br. s., 1H), 3.82 (s, 3H), 3.97 (s, 2H), 4.09 (d, J=18.0 Hz, 1H), 4.33 (d, J=18.0 Hz, 1H), 4.91 (dd, J=8.8, 6.1 Hz, 1H), 5.04 (s, 1H), 6.66-6.73 (m, 2H), 6.76 (d, J=7.8 Hz, 1H), 6.82 (dd, J=8.3, 1.7 Hz, 1H), 7.28-7.35 (m, 2H), 8.95 (br. s., 1H).
