Reaction Steps

6-chloro-N-(3-(3,5-dimethoxyphenylamino)quinoxalin-2-yl)-pyridine-3-sulfonamide (100 mg, 0.21 mmol), prepared using procedures similar to those used in Example 8, KHCO3 (40 mg, 0.40 mmol), N1,N1-dimethylethane-1,2-diamine (225 μL, 2.0 mmol) and dry DMF (1.0 mL) were combined and heated to 130° C. with stirring overnight. The reaction mixture was concentrated in vacuo and purified by preparative HPLC to give N-(3-(3,5-dimethoxy-phenylamino)-quinoxalin-2-yl)-6-(2-(dimethylamino)ethylamino)pyridine-3-sulfonamide (21.0 mg, 19%). 1H NMR (400 MHz, DMSO-d6) δ 8.76 (br s, 1H), 8.63 (d, 1H), 8.07 (dd, 1H), 7.40 (m, 1H), 7.34 (m, 1H), 7.28 (d, 2H), 7.14 (m, 4H), 6.47 (d, 1H), 6.12 (m, 1H), 3.75 (s, 6H), 3.35 (m, 2H), 3.14 (m, 2H), 2.74 (s, 6H). MS (EI) m/z for C25H29N7O4S: 524.1 (MH+).
