Procedure
To a suspension of 0.7 g of N-[[[4-(1,4,5,6-tetrahydro-6-oxo-3-pyridazinyl)phenyl]amino]thioxomethyl]benzamide in 7 ml of ethanol is added 1.6 ml of 10% ethanolic sodium hydroxide followed by heating for two hours. The reaction mixture is cooled, diluted with water, and filtered to give 0.4 g of the product, N-[4-(1,4,5,6-tetrahydro-6-oxo-3-pyridazinyl)phenyl]thiourea mp 234°-235° C.
