実験手順

N-[2-(6-Methyl-2-methylsulfanyl-pyrrolo[2,1-f][1,2,4]triazin-7-yl)-phenyl]-methanesulfonamide was prepared in an analogous fashion to Example 47a after: replacing 2-methoxybenzeneboronic acid with N-[2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-phenyl]-methanesulfonamide, and replacing 7-Bromo-2-methylsulfanyl-pyrrolo[2,1-f][1,2,4]triazine with 7-Bromo-6-methyl-2-methylsulfanyl-pyrrolo[2,1-f][1,2,4]triazine, to give after purification via normal phase chromatography (EtOAc/hexane as eluant) N-[2-(6-Methyl-2-methylsulfanyl-pyrrolo[2,1-f][1,2,4]triazin-7-yl)-phenyl]-methanesulfonamide as a yellow solid (0.12 g, 44%). LC/MS (E/I+) 349.04 (M+H).
