Procedure

The 6-(p-tert.-butylbenzoyl)-3-chloro-5,6,7,8-tetrahydropyrido[4,3-c]pyridazine, required as starting material, may be obtained in a manner analogous to that described in Example 8(g), from 34.2 g of 3-chloro-5,6,7,8-tetrahydropyrido[4,3-c]pyridazine maleate and 25 g of tert.butylbenzoyl chloride. M.P. 157°-160° (decomp., from 95% ethanol).
