Versuchsvorschrift

In 30 ml of chloroform were added 3 g of 4-nitrobenzoyl chloride, 3.3 g of 2-aminoethyl bromide hydrobromide and 3.9 ml of pyridine under ice cooling, and they were stirred at the same temperature for 1 hour. The reaction mixture was then washed with water, and the resulting organic layer was concentrated to obtain a crude product of 2-(4-nitrobenzoylamino)ethyl bromide. Afterward, the latter was recrystallized from hexane/ethanol, the resulting crystals were collected by filtration, washed and dried to prepare 2.9 g of 2-(4-nitrobenzoylamino)ethyl bromide (compound 46).
