실험 절차

To a solution of 0.40 gm (1.04 mMol) 5-(2-chloro-4-fluorobenzoyl)amino-3-(1-methyl-1,2,3,6-tetrahydropyridin-4-yl)-1H-indole in 5.2 mL trifluoroacetic acid were added 0.208 mL (1.3 mMol) triethylsilane and the reaction mixture was stirred at ambient. After 2 hours, the reaction mixture was concentrated under reduced pressure. To the residue was added 2N sodium hydroxide and the aqueous was extracted with dichloromethane. The combined organic extracts were washed with 2N sodium hydroxide, dried over sodium sulfate and then concentrated under reduced pressure to give an orange foam. The foam was subjected to radial chromatography (2 mm silica), eluting with 100:10:1 dichloromethane:methanol: ammonium hydroxide. The residue was crystallized from ethyl acetate/hexanes to give 0.27 gm (67.3%) of the title compound as a burnt orange powder.
