Versuchsvorschrift

5-fluoro-3-(5-fluoro-4-methylsulfanyl-pyrimidin-2-yl)-1-(p-tolylsulfonyl)pyrrolo[2,3-b]pyridine, 24a, (2.30 g, 5.32 mmol) was dissolved in dichloromethane (107 mL) and treated portionwise with 3-chloroperbenzoic acid (1.19 g, 5.30 mmol), keeping the temperature below 20° C. After stirring for 2 hours, another portion of 3-chloroperbenzoic acid (0.18 g, 0.80 mmol) was added, and stirring was continued for another hour. A third portion of 3-chloroperbenzoic acid (0.07 g, 0.05 mmol) was added and stirring was continued for 30 minutes. The reaction mixture was treated with an aqueous 15% K2CO3 solution (30 mL) and the layers were separated. The organic layer was washed with 15% K2CO3 and brine, dried (Na2SO4), filtered and concentrated in vacuo to afford 2.3 g (96%) of the desired product as a yellow solid, which was used without further purification: 1H NMR (300 MHz, DMSO-d6) δ 9.12 (d, J=1.5 Hz, 1H), 8.70 (s, 1H), 8.67 (dd, J=9.1, 2.8 Hz, 1H), 8.53 (d, J=1.5 Hz, 1H), 8.11 (d, J=8.4 Hz, 2H), 7.46 (d, J=8.2 Hz, 2H), 3.05 (s, 3H), 2.36 (s, 3H).
