Procedure

A solution of 4-chlorobenzyl bromide in acetone was treated with NaN3 and refluxed for 3 hours. The reactions was concentrated by 50% and diluted with saturated sodium chloride solution. The reaction was then extracted with Et2O, washed with brine, dried (Na2SO4) and concentrated to give 1-(azidomethyl)-4-chlorobenzene.
