Versuchsvorschrift

The 6-benzoyl-5,6,7,8-tetrahydro-3-mercaptopyrido[4,3-c]pyridazine, required as starting material, may be obtained in a manner analogous to that described in Example 41 (a), from 27.4 g of 6-benzoyl-3-chloro-5,6,7,8-tetrahydropyrido[4,3-c]pyridazine and 8.4 g of thiourea. After cooling the reaction mixture with ice, the compound precipitates. M.P. 225°-228° (decomp., from glacial acetic acid).
