실험 절차

A 1.0 g quantity (0.005 mols) of 2-phenyl-2-(3-pyridazinyl)acetonitrile was dissolved in 50 ml of dry pyridine in a sealed tube, and 4 ml of triethylamine was added. After allowing the resulting solution to stand for 1.5 hours, dry hydrogen sulfide was passed through the solution in a steady stream at room temperature for 15 minutes. The sealed mixture was then left to stand at room temperature for 24 hours. The reaction mixture was concentrated in a vacuum to give a yellow solid cake. Recrystallization of the concentrate from ethanol afforded 1.1 g (94% yield) of 2-phenyl-2-(3-pyridazinyl)thioacetamide in the form of pale yellow plates, m.p. 161° to 163° C.
