An additional amount of sodium azide (1.2 g) and ammonium (1.0 g) is added and stirring resumed at 140° C. for 17 hours. The mixture is poured over ice and acidified with hydrochloric acid. The crude product solidifies and is filtered off to give 11 g of crude product. The crude product is slurried with hot methanol and filtered off. To a hot solution of this material is added enough water to cause trubidity. On cooling the compound crystallizes and is filtered off to yield 5.0 g of pure material having a M.P. of 200°-205° C. dec.
