実験手順
3-Keto-4-cyanotetrahydrothiophene (80 g, 0.629 mol) and o-phenylenediamine (68 g, 0.629 mol) were dissolved by heating in 1.5 liters of industrial methylated spirit. To the solution, glacial acetic acid (3 ml) was added, the solution then being heated under reflux with mechanical stirring for 24 hours. The solution was then chilled and filtered to give the title product as a solid, m.p. 163° C.
