2-Bromopropiophenone → 5Benzyloxy-3-methyl-2-phenyl-1H-indole

Participants

Reaction Steps

An amount of 3.6 g (0.015 mole) of 2-bromo-propiophenone and 6 g (0.03 mole) of 4-benzyloxy-aniline were refluxed for two hours in 15 ml of triethylamine. The mixture was evaporated to dryness, and the residue was heated for two hours to 180° C. After cooling, the residue was mixed with 10% hydrochloric acid and extracted with chloroform. The extracts were dried over sodium sulfate, filtered, and evaporated. The residue obtained was purified by column chromatography on silicagel with toluene as solvent.
