Reaction Steps

The titled compound was prepared in analogous fashion as Example 113 using N-tert-butyl-3-(2-methanesulfinyl-pyrrolo[2,1-f][1,2,4]triazin-7-yl)-benzenesulfonamide and 7-amino-4-methyl-4H-benzo[1,4]oxazin-3-one to give N-tert-butyl-3-[2-(4-methyl-3-oxo-3,4-dihydro-2H-benzo[1,4]oxazin-7-ylamino)-pyrrolo[2,1-f][1,2,4]triazin-7-yl]-benzenesulfonamide as a light tan solid (51.6 mg, 35.7% yield).
