Versuchsvorschrift

A mixture of diphenylacetonitrile (7.0 g), hydroxylamine hydrochloride (3.03 g), and sodium acetate (6.67 g) in 150 ml of 5:1 ethanol-water was refluxed for 4 h. The mixture was concentrated under reduced pressure. The residue was triturated with water, filtrated, and dried to give the title compound (2.5 g) having the following physical data.
