반응 단계
A solution of 5.0 g N-ethyl-N[3-(6-chloro-3-pyridazinyl)phenyl]propanamide and 3.8 g of 4-methylthiosemicarbazide in 200 ml ethanol was refluxed for 18 hours. The mixture was then treated and the product chromatographed as described for Example 70. Recrystallization of the product from acetone-hexane afforded 0.5 g orange crystals, mp 172°-173° C.
