Versuchsvorschrift

Potassium tert-butoxide (410 mg, 3.6 mmol) is added to a mixture of 7-methyl-1H-indole (470 mg, 3.6 mmol) in DMSO (20 ml) with ice cooling. Stirring is continued for 10 minutes before 2,4,6-trifluoropyridine E (350 μl, 3.6 mmol) is added dropwise. The mixture is warmed to RT and stirred for 2 h. The mixture is diluted with DCM and extracted with water. The combined organic layers are dried over MgSO4 and concentrated in vacuo. The product is purified by RP HPLC. Yield: 350 mg (40%). HPLC-MS: M+H=245; tR=1.03 min (Method—2).
