Versuchsvorschrift
261 g) Into a round-bottom flask, m-chloroperbenzoic acid (77% by weight in benzoic acid, 853 mg, 3.80 mmol) was added to a solution of 2-methylsulfanyl-[1,2,4]triazino[1,6-a]indole (780 mg, 3.60 mmol) in dichloromethane (20 mL), at 0° C. The reaction was stirred for 1 hour at room temperature. Saturated NaHCO3 in water was added and the reaction mixture was stirred for 30 minutes. The organic phase was separated, washed with brine, and dried over magnesium sulfate, then filtered. The solvent was removed under vacuum to afford 2-methanesulfinyl-[1,2,4]triazino[1,6-a]indole (820 mg, 98%) as an orange solid, which was used without further purification. 1H-NMR (CDCl3) δ 9.28 (s, 1H), 8.34 (d, J=8.5 Hz, 1H), 7.95 (d, J=8.1 Hz, 1H), 7.60 (m, 1H), 7.52 (m, 1H), 7.21 (s, 1H), 3.06 (s, 3H); LC/MS (ESI+): 254.5 (M+Na).
