A solution of 5.0 g N-methyl-N-[3-(6-chloro-3-pyridazinyl)phenyl]propanamide and 4.3 g 4-ethyl-3-thiosemicarbazide was refluxed for 18 hours. The mixture was then treated and the product chromatographed as described in Example 70. Recrystalization of the product from dichloromethane-hexane afforded 1.2 g of yellow crystals, mp 198°-199° C.
