Reaktionsschritte
To a solution of 16.5 g. of 2-nitro-4-chlorobenzyl alcohol in 200 ml. of chloroform was added dropwise 13 g. of phosphorus tribromide, and the mixture was heated to reflux for 1 hour on a water bath. The reaction mixture was then poured into water, and the chloroform layer was separated and washed with water. After the solvent was removed, the residue was extracted with ligroin while warming and allowed to stand to form colorless acicular crystals of 2-nitro-4-chlorobenzyl bromide (80% yield) melting at 42° to 43° C.
