The synthetic route is as follows., HPLC of Formula: C6H8Br4
4-Hydroxy benzonitrile (3) (1.19 g, 10 mmol) and potassium hydroxide (0.56 g, 10 mmol) were dissolved in absolute ethanol. 1,1,2,2-tetrayl-tetramethylene-tetrabromide (1) (1.00 g, 2.5 mmol) was then added into this solution. The reaction mixture was refluxed for 8 h. The solution was cooled and filtrated. The white solid obtained was washed with H2O, alcohol and crystallized from DMF. Yield: 1.14 g (83%). mp 212-214 C.
