Procedure
A mixture of 3.77 g of 4-(4-chlorophenyl)-5-hydroxy-5-methyl-3-(3-thienyl)-2(5H)-furanone, 0.73 g of hydrazine monohydrate and 30 ml of 1-butanol was heated under reflux for 0.5 hours. The reaction mixture was cooled to 0° C. The deposited solid was collected by filtration. The solid was washed with a mixed solvent of hexane and t-butyl methyl ether, and dried under reduced pressure, to obtain 1.49 g of 5-(4-chlorophenyl)-6-methyl-4-(3-thienyl)-2H-pyridazin-3-one.
