Versuchsvorschrift

Into a RB flask, N-[5-Methyl-2-(2-methylsulfanyl-pyrrolo[2,1-f][1,2,4]triazin-7-yl)-phenyl]-methanesulfonamide (580 mg, 1.7 mmol) and N,N-Dimethylformamide (13 mL,) were added. Resulting solution was cooled to 0° C., m-CPBA (70:30, m-Chloroperbenzoic acid:3-Chlorobenzoic acid, 431 mg, 1.75 mmol) was added in portion over 10 minutes. After 2 h, solvent was removed .The residue was partitioned with DCM and sat. NaHCO3 solution. The organic phase was separated, washed with brine, and dried over Magnesium sulfate. N-[2-(2-Methanesulfinyl-pyrrolo[2,1-f][1,2,4]triazin-7-yl)-5-methyl-phenyl]-methanesulfonamide was obtained as a yellow solid (539 mg, 89%) which was taken to the next step without further purifications. LCMS (E/I+) 365 (M+H).
