Reaction Steps

The starting material may be prepared as follows: To a solution of 1.92 g of 2,6-dichloro-4-phenylquinazoline in 30 ml of dimethylsulfoxide was added 0.91 g of sodium azide. The mixture was heated at 100° C. for 1 hour with stirring and then poured into ice-water. The resulting precipitate was collected by filtration, washed with water and dried to give 1.9 g of 7-chloro-5-phenyltetrazolo[1,5-a]quinazoline. Recrystallization from chloroform-ethanol gave pale yellow needles, m.p. 209° C. (decomp.).
