Sodium Azide → 4-(Azidomethyl)benzonitrile

Participants

Reaction Steps

A solution of 20.23 g (0.31 mol) sodium azide in 50 ml water was added to 49.15 g (251 mmol) 4-cyanobenzyl bromide in 200 ml DMF at ambient temperature. An exothermic reaction took place and after 1.5 h the reaction mixture was diluted with 200 ml toluene(caution: In order to avoid separation of potentially explosive azide compounds it is adviseable to add the toluene to the reaction mixture before addition of the water) and 500 ml water. The aqueous phase was extracted with an additional 2×50 ml toluene. The combined organic extracts were washed with 2×50 ml water and brine and finally dried (MgSO4) and filtered.
