실험 절차

To a solution of the compound of N-(5-(5-bromo-1H-benzo[d]imidazol-1-yl)-2′,4′-difluoro-[1,1′-biphenyl]-3-yl)cyclopropanesulfonamide (110 mg, 0.198 mmol) in DMSO was added potassium carbonate (54 mg, 0.391 mmol, 2.0 eq.). The mixture was degassed by N2 bubbling for 10 min followed by addition of 1-ethylpiperazine (68 mg, 0.595 mmol, 3.0 eq.) and L-proline (4.5 mg) and CuI (3 mg). Then seal tube was closed and the mixture was kept at 95° C. for 24 h. The mixture was quenched and extracted as in Example 1(d). The solvent was distilled off to afford the crude residue which was purified by preparative HPLC to give the product in 18% yield (20 mg). 1H NMR (400 MHz, DMSO-D6): δ10.3 (s, 1H), 8.98 (s, 1H), 7.77 (m, 1H), 7.66 (s, 1H), 7.60 (brs, 2H), 7.50 (brs, 2H), 7.41 (s, 1H), 7.33-7.27 (m, 2H), 3.60 (m, 4H), 3.29-3.20 (m, 4H), 3.02 (q, 2H), 2.90 (t, 1H), 1.30 (t, 3H), 1.04 (q, 4H), LC-MS (ESI): Calculated mass: 537.62; Observed mass: 538.1 [M+H]+
