実験手順

An oven-dried, argon-sparged vial was charged with 4-bromo-2,N,N-trimethyl-benzenesulfonamide (70 mg, 0.25 mmol), 2,5-dimethyl-1-(2-trifluoromethyl-phenyl)-1H-pyrrole-3-carboxamide (85 mg, 0.30 mmol), anhyd K2CO3 (69 mg, 0.50 mmol), and copper (I) iodide (10 mg, 0.05 mmol), and then briefly sparged with argon. To the vial under argon was added anhyd toluene (0.5 mL) and N,N′-dimethyl-ethylenediamine (11 μL, 0.10 mmol), then capped and heated at 120° C. After 24h the reaction mixture was cooled, diluted with EtOAc, filtered through Celite and concentrated under reduced pressure. The crude material was chromatographed (silica, EtOAc/Hex, 0:100 to 50:50) to afford the title compound (95 g, 79%) as a white solid. 1H-NMR (DMSO-d6) δ 9.74 (1H, s), 8.01 (1H, d, J=7.8), 7.92 (1H, app t, J=7.8), 7.78-7.86 (3H, m), 7.71 (1H, d, J=8.3), 7.51 (1H, d, J=7.8), 6.65 (1H, s), 2.69 (6H, s), 2.53 (3H, s), 2.14 (3H, s), 1.88 (3H, s); MS (ESI): 480 (MH+).
