3,4-DICHLOROPHENACYL BROMIDE Chemical Properties,Usage,Production

Uses

2-Bromo-3',4'-dichloroacetophenone is a chemical ragent used in the synthesis of 2-aroylbenzoxazoles. As well, it is used in the synthesis of aminoarylthiazole derivatives as correctors of chloride transport defect in cystic fibrosis patients.

Synthesis

2642-63-9

2632-10-2

General procedure for the synthesis of alpha-bromo-3,4-dichloroacetophenone from 3,4-dichloroacetophenone: to a solution of 3,4-dichloroacetophenone (18.8 g, 0.1 mol, 1.0 eq.) in acetonitrile (100 ml) was added p-toluenesulfonic acid (25.8 g, 0.15 mol, 1.5 eq.) and N-bromosuccinimide (17.7 g, 0.1 mol. 1.0 equiv). The reaction mixture was refluxed at 80 °C for 5 hours. After completion of the reaction, the organic phase was extracted and concentrated, and purified by silica gel column chromatography to afford α-bromo-3,4-dichloroacetophenone (95% yield).
