実験手順

5-[(2-Fluoro-4-iodophenyl)methyl]-2-(2-fluorophenyl)-2,5-dihydro-3H-pyrazol[4,3-c]quinolin-3-one [(Example 187, Step 2), 68 mg, 0.13 mmol], pyrazole (18 mg, 0.26 mmol, 2 equiv) and copper(I) iodide (10 mg, 0.053 mmol, 0.4 equiv) were combined in a sealed tube, to which was added dimethylsulfoxide (1 mL), (±)-trans-N,N′-bismethyl-1,2-cyclohexane diamine (15 mg, 0.11 mmol, 0.8 equiv) and an aqueous (0.2 ml) solution of potassium phosphate (84 mg, 0.40 mmol, 3 equiv). The vessel was flushed with nitrogen, sealed and placed into a preheated oil bath at 100° C. for 1 hour. The mixture was cooled to ambient temperature, poured into water (15 mL) and extracted with chloroform (2×15 mL). The combined organic extracts were washed once with water (5 mL) and brine (5 mL), dried with sodium sulfate, filtered and concentrated in vacuo. The residue was purified by silica gel gradient chromatography (100:0 to 90:10; chloroform:methanol), providing the titled compound: 1H-NMR (400 MHz, d6-DMSO) δ 9.09 (1H, s), 8.54 (1H, d, J=2.6 Hz), 8.21 (1H, dd, J=7.9, 1.5 Hz), 7.82 (1H, dd, J=11.9, 2.1 Hz), 7.73-7.73 (2H, m), 7.68-7.59 (3H, m), 7.55 (1H, t, J=7.6 Hz), 7.49-7.32 (4H, m), 6.56 (1H, dd, J=2.3, 2.0 Hz), 5.82 (2H s) ppm; high resolution mass spectrometry (ES+) m/z 454.1467 [(M+H)+; calculated for C26H18F2N5O: 454.1474].
