Reaction Steps

2-Methanesulfinyl-7-(2-methoxy-phenyl)-pyrrolo[2,1-f][1,2,4]triazine (125.0 mg, 0.0004350 mol), N,N-Diisopropylethylamine (0.114 mL, 0.000652 mol) and 1H-Imidazo[4,5-c]pyridine (0.104 g, 0.000870 mol) were dissolved in 1-Methoxy-2-propanol (1.2 mL, 0.013 mol) and the reaction was irradiated at 300 watts, 180° C. for 40 minutes or until HPLC showed consumption of starting material. The reaction mixture was then reduced en vacuo and the product was isolated and purified by Gilson prep HPLC to afford 43.80 mg of 1-[7-(2-Methoxy-phenyl)-pyrrolo[2,1-f][1,2,4]triazin-2-yl]-1H-imidazo[4,5-c]pyridine (mixture of regioisomers) as a lyophilized powder. (M+H)=343.7. 1H NMR (400 MHz, DMSO, d6) δ 9.35 (s, 1H), 9.15 (s, 1H), 8.47 (d, 1H, J=5.52 Hz), 8.09 (d, 1H, J=5.45 Hz), 7.81 (m, 2H), 7.57 (m, 1H), 7.32 (m, 3H), 7.23 (m, 1H), 3.82 (s, 3H).
