Participants

Reaction Conditions

Reaction Steps

Dibromoethane (5.25 g, 0.049 mol) and 2,4-dinitrophenol (3 g, 0.016 mol) were added to dimethylformamide (20 ml) and, after adding a fine powder of potassium carbonate (2.24 g), the mixture was heated at 85° C. for 1.5 h. Thereafter, the solvent was evaporated and three extractions were conducted with ethyl acetate. The organic extracts were combined and dried with sodium sulfate, with the residue being subjected to column chromatography on silica gel using methylene chloride as an eluent. The fractions containing the end product were collected and the solvent was evaporated to yield the end compound 2,4-dinitrophenoxyethly bromide (1.64 g).
