Procedure

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 1-[4-(3-Amino-phenyl)-piperazin-1-yl]-2-methyl-propan-2-ol (0.217 g, 0.000870 mol) were dissolved in 1-Methoxy-2-propanol (1.2 mL) and the reaction was microwaved on 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 provide 29.84 mg of 1-(4-{3-[7-(2-Methoxy-phenyl)-pyrrolo[2,1-f][1,2,4]triazin-2-ylamino]-phenyl}-piperazin-1-yl)-2-methyl-propan-2-ol as a lyophilized powder.
