Komponenten

Versuchsvorschrift

To 10 grams (0.05 mole) of 4-nitrophenylchloroxime are added 150 milliliters of ethanol and a catalytic amount of 4-(N,N-dimethyl)aminopyridine. 4.0 grams of 2-amino-4-nitrophenol are added to the mixture. The mixture is stirred under nitrogen at room temperature for ninety minutes, at which time another 3.7 grams of 1-amino-4-nitrophenol are added. The mixture is then stirred overnight at room temperature under a nitrogen blanket, cooled to 20° C. and filtered to yield 2-(p-nitrophenyl)-5-nitrobenzoxazole.
