Participants

Reaction Steps

A solution of hydroxylamine hydrochloride (0.08 mol) in anhydrous ethanol (50 cm3) was added dropwise to a stirred solution of 4-(4-pyrrolidinophenyl)-1,2-naphthoquinone (0.02 mol) in warm anhydrous ethanol (250 cm3). The mixture was refluxed until thin layer chromatography indicated that no 4-(4-pyrrolidinophenyl)-1,2-naphthoquinone remained. The mixture was cooled in ice, diluted with water and the brown precipitate was collected by vacuum filtration and washed with water and air dried. Yield=84%, m.p.=278-300° C. (decomp.).
