General description

Diphenylacetonitrile can be prepared in good yield by the dehydration of the amide of diphenyl acetic acid with phosphorous oxychloride.

Application

Diphenylacetonitrile undergoes anhydrous condensation with ethyl-4-bromo-butyrate. This is followed by its hydrolysis in alkaline medium that is used in the quantitative determination of 3-cyano-3,3-diphenylpropionic acid.

A sensitive gas chromatographic procedure with nitrogen-phosphorus detection was developed for the quantitative determination of 3-cyano-3,3-diphenylpropionic acid, the acidic metabolite of the narcotic analgesic bezitramide (Burgodin). Gas chromatography with mass spectrometric detection was used for confirmation. An internal standard, 5-cyano-5,5-diphenylvaleric
