Participants

Reaction Conditions

Reaction Steps

A mixture of 3-nitrobenzonitrile (3.70 g, 25 mmol), sodium azide (4.88 g, 75 mmol) and triethylamine hydrochloride (10.32 g, 75 mniol) in N-methylpyrrolidone (55 ml) was heated at 130° C. for 2 hours under stirring. The reaction mixture was poured into ice-water, to which was dropwise added 6N hydrochloric acid in order to acidify. The resultant precipitates were collected by filtration, washed with water and dried to afford 5-(3-nitrophenyl)-1H-tetrazole (4.45 g, 93.1%), which was used in a following reaction without further purification.
