실험 절차
A mixture of 6 g of 6-chloro-7,8,9,10-tetrahydrotetrazolo[5,1-a]phthalazine, 150 ml of methanol and excess pyrrolidone was heated on a boiling-water steam bath for 10 minutes and cooled. The solid which formed was separated by filtration, washed with water and recrystallized from a mixture of dimethylsulfoxide and water to give 6-(1-pyrrolidinyl)-7,8,9,10-tetrahydrotetrazolo[5,1-a]phthalazine melting at about 272°-273° C.
