1,4-Dibromobutane → HCID 15611140, compound

Participants

Reaction Steps

A suspension of 7.5 g of 2-hydroxy-N-(1H-indol-4-yl)benzamide and 8.28 g of potassium carbonate in 150 ml of acetone was refluxed for 75 minutes with 18 ml of 1,4-dibromobutane and the mixture was cooled. The precipitate was filtered off and rinsed with acetone and the filtrate was evaporated to dryness. The residue was purified by chromatography over silica (eluant: methylene chloride/ethyl acetate 9:1), followed by crystallization from ethyl acetate to obtain 2-(4-bromobutoxy) -N-(1H-indol-4-yl)benzamide melting at 135° C.
