Reaction Steps
A mixture of 500 mg of 5-bromo-3,4-dihydroxybenzaldehyde and 700 mg of sulfonly diacetonitrile in 6 ml of ethanol was refluxed with few drops of piperidine for 4 hours. Ethanol was removed in rotavap and the mixture worked up with ethyl acetate, diluted acid and brine. A portion of the crude was then purified by HPLC on a C-18 column to provide about 50 mg of 2-(3-bromo-4,5-dihydroxyphenyl)-1-cyano-1-cyanomethylsulfonly ethene.
