Participants

Reaction Steps

A stirred mixture of 5.0 g (0.016 mole) of the triethylammonium salt of 4-chloro-2-fluorophenyl dithiocarbamic acid, 0.62 g (0.016 mole) of sodium hydroxide, and 4.0 g (0.062 mole) of sodium azide in 10 ml of water was heated at reflux for three hours. The mixture was cooled to room temperature and was acidified with concentrated hydrochloric acid. A precipitate formed and was collected by filtration. The filter cake was washed with water and was dried to yield 3.2 g of 1-(4-chloro-2-fluorophenyl)-1,4-dihydro-5H-tetrazol-5-thione, m.p. 128° C.
