A mixture of 6-chloro-3-phenyl-1,2,4-triazolo[3,4-a]phthalazine (5 g), pyrrolidine (5 ml), ethanol (35 ml) and catalytic amounts of KI, is poured in a pressure resistant vessell and heated to 100° C. for 8 hours. The reaction mixture is then cooled, the solvent is evaporated off and the residue is thoroughly washed with a small amount of water and crystallized from ethanol yielding the compound of the title in 82% yield. M.p. 208°-09° C.
