Participants

Reaction Steps

A mixture of 4-benzoyl-3,5-dichlorobenzyl bromide (2.37 g, 6.89 mmol) and sodium azide (1.32 g, 20:3 mmol) in absolute ethanol (31 ml) was refluxed 5 hours, cooled, and evaporated. The residue was dissolved in diethyl ether and filtered. The filtrate was evaporated to provide 1.95 g (92%) 4-benzoyl-3,5-dichorobenzyl azide, IR (neat): 2090, 1670 cm-1.
