실험 절차

To a mixture of 5-bromo-4-(4-((1-methyl-1H-imidazol-5-yl)methyl)piperazin-1-yl)-3-nitropyridin-2-amine (0.030 g, 0.076 mmol, 1 eq), EtOH (1.95 mL) and DMF (0.29 mL), 4-(morpholinomethyl)-benzaldehyde (0.017 g, 0.083 mmol, 1.1 eq) was added followed by a freshly prepared aqueous solution of Na2S2O4 (1M; 0.23 mL, 0.23 mmol). The reaction mixture was heated at 85° C. for 24 h, then allowed to cool to room temperature and diluted with DCM and a few drops of aqueous NH3 until complete dissolution was observed. This solution was deposited on two preparative silica TLC plates and eluted with DCM/MeOH (v/v; 94:6). The title compound was obtained after trituration with diethyl ether as a yellow solid (0.005 g, 14.7%); 1H-NMR (500 Mz, DMSO-d6): δ 2.35-2.41 (m, 4H), 2.55-2.62 (m, 4H), 3.52-3.55 (2 s, 4H, 2NCH2), 3.59 (t, J=4.5 Hz, 4H), 3.62-3.67 (m, 4H), 3.68 (m, 3H, imidazole Me), 6.80 (s, 1H, imidazole 4-H), 7.46 (d, J=8.0 Hz, 2H, ArH, C6H4), 7.57 (s, 1H, imidazole 2-H), 8.13 (d, J=8.0 Hz, 2H, ArH, C6H4), 8.23 (s, 1H, imidazo[4,5-b]pyridine 5-H), 13.47 (br s, 1H, imidazo[4,5-b]pyridine N—H); LC (Method B)-MS (ESI, m/z): R=1.79 min—551/553 [(M+H+), Br isotopic pattern, 100%]; ESI-HRMS: Found: 551.1882, calculated for C26H32N8OBr (M+H)+: 551.1882.
