Procedure

A mixture of 3,4-dichlorobenzyl chloride (10 g, 0.05 mol), sodium azide (5 g, 0.08 mol) in DMSO (100 mL) was stirred at room temperature overnight. The mixture was poured into water (150 mL). The water layer was extracted with ethyl acetate (100 ml×3). The combined organic phases were dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by distillation to give the title compound as an oil (14 g, quantitative yield). LC/MS: m/z 203 (M+H)+, Rt: 2.26 min.
