In a 10 mL sealed tube, to N-tert-Butyl-3-(2-hydroxy-pyrrolo[2,1-f][1,2,4]triazin-7-yl)-benzenesulfonamide (100 mg, 0.289 mmol) and N,N-Diisopropylethylamine (0.202 mL, 1.16 mmol) in 3.0 mL of anhydrous DMF was added N-Phenylbis(trifluoromethane-sulfonimide (113 mg, 0.318 mmol). After stirring at room temperature for 30 minutes, 2-Methoxy-4-(1-methyl-piperidin-4-yl)-phenylamine (84 mg, 0.36 mmol) was added. The reaction mixture was heated at 65° C. overnight. The reaction was conc. in vacuo. The reaction mixture was purified via silica gel column chromatography using 500:12:8 DCM:MeOH:7N NH3/MeOH as the eluant. The collected fractions afforded N-tert-Butyl-3-{2-[2-methoxy-4-(1-methyl-piperidin-4-yl)-phenylamino]-pyrrolo[2,1-f][1,2,4]triazin-7-yl}-benzenesulfonamide as a yellow solid (19.66 mg, 11%). MP 189-198° C.
