実験手順

To a solution of (S)-3-cyclopentyl-2-(1-oxo-4-trifluoromethyl-1,3-dihydro-isoindol-2-yl)-propionic acid (prepared as in Example 1, 71 mg, 0.21 mmol) and 1-(2-methoxy-ethyl)-1H-pyrazol-3-ylamine (prepared as in US 20080021032, Example 72, 32 mg, 0.23 mmol) and benzotriazole-1-yl-oxy-tris-(dimethylamino)-phosphonium hexafluorophosphate (Chemimpex, 0.11 g, 0.25 mmol) in methylene chloride (5 mL) was added N,N-diisopropylethylamine (0.11 mL, 0.62 mmol) dropwise and the resulting solution stirred at room temperature over night. The solution was diluted with methylene chloride, washed with a 1 N hydrochloric acid solution (15 mL), a saturated sodium bicarbonate solution (20 mL) dried over magnesium sulfate. The mixture was filtered and evaporated and the resulting material purified via automated flash chromatography (Analogix, SF4-12 g column, 50-80% ethyl acetate/hexanes) to give (S)-3-cyclopentyl-N-[1-(2-methoxy-ethyl)-1H-pyrazol-3-yl]-2-(1-oxo-4-trifluoromethyl-1,3-dihydro-isoindol-2-yl)-propionamide (42 mg, 43%) as an off white solid: HR-ES(+) m/e calcd for C23H27N4O3F3 [M+H]+ 465.2108, observed 465.2107; 1H NMR (300 MHz, DMSO-d6) δ ppm 1.04-2.18 (m, 10H), 3.20 (s, 3H), 3.51-4.28 (m, 4H), 4.60-5.34 (m, 3H), 6.40 (d, J=1.81 Hz, 1H), 7.41-8.28 (m, 5H), 10.93 (s, 1H).
