Procedure

The 3-chloro-6-(2-naphthoyl)-5,6,7,8-tetrahydropyrido[4,3-c]pyridazine, required as starting material, is produced in a manner analogous to that described in Example 8(g), from 3-chloro-5,6,7,8-tetrahydropyrido[4,3-c]pyridazine maleate and 2-naphthoyl chloride. Reaction time 22 hours at room temperature. M.P. 167°-170°(decomp., from 95% ethanol).
