Procedure

2-Methanesulfinyl-7-(6-methoxy-pyridin-3-yl)-pyrrolo[2,1-f][1,2,4]triazine (125.0 mg, 0.0004335 mol), N,N-Diisopropylethylamine (0.249 mL, 0.00143 mol) and 5-Amino-1-methyl-1,3-dihydro-indol-2-one (0.141 g, 0.000867 mol) were dissolved in 1-Methoxy-2-propanol (0.498 mL, 0.00510 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 13.85 mg of 5-[7-(6-Methoxy-pyridin-3-yl)-pyrrolo[2,1-f][1,2,4]triazin-2-ylamino]-1-methyl-1,3-dihydro-indol-2-one as a lyophilized powder. (M+H)=387.1. 1H NMR (400 MHz, DMSO, d6) δ 9.40 (s, 1H), 8.96 (s, 2H), 8.47 (d, 1H, J=8.73 Hz), 7.82 (s, 1H), 7.51 (d, 1H, J=8.40 Hz), 7.16 (d, 1H, J=4.37 Hz), 7.04 (d, 1H, J=8.65 Hz), 6.91 (m, 2H), 3.95 (s, 3H), 3.59 (s, 2H), 3.12 (s, 3H).
