Ethyl Acetate → HCID 21846284, compound

Participants

Reaction Steps

4-Acetylindole (0.101 g) was refluxed in 5 mL of ethyl acetate. Sodium hydride (0.20 g, 60% oil dispersion) was added in portions to the refluxing solution until thin layer chromatography analysis showed complete consumption of the starting material. The reaction mixture was quenched with water and acidified to pH 3. The ethyl acetate layer was dried (magnesium sulfate) and concentrated to give a crude product. The crude material was chromatographed on silica gel, eluting with hexane/ethyl acetate to give 1-(1H-indol-4-yl)-1,3-butanedione (0.104 g), a compound of formula (11), m.p. 104-105° C.
