Versuchsvorschrift
To a suspension of 9.9 g of 1-chloro-4-hydrazino-5,6,7,8-tetrahydrophthalazine in 35 ml of aqueous 12% acetic acid was added a solution of 3.5 g of sodium nitrite in 30 ml of water. The mixture was kept at room temperature (about 22°-25° C.) for about 20 minutes. The solid present was then separated by filtration, air dried and recrystallized to give 6-chloro-7,8,9,10-tetrahydrotetrazolo[5,1-a]phthalazine melting at about 109°-110° C.
