Procedure

A mixture of 100 mg of 3-oxo-6-pyridin-4-yl-2,3-dihydro-pyridazine-4-carboxylic acid hydrazide, 130 mg thioacetamide, 87 mg triethylamine, 1 ml of pyridine and 5 ml of butanol is refluxed for 15 hours. After cooling and stirring at room temperature a solid precipitated is collected by filtration, washed with cold isopropanol and dried in vacuo.
