Procedure

A solution of 3.4 g of 6-benzoyl-5,6,7,8-tetrahydro-3-mercaptopyrido[4,3-c]pyridazine in 40 cc of methylhydrazine is stirred at a bath temperature of 110° for 11/2 hours. The oil obtained after concentrating the mixture in a vacuum is taken up in absolute ethanol, and the calculated amount of gentisic acid is added. After standing for some time the crystalline bisgentisinate of the title compound is obtained.
