Reaction Steps
A mixture of benzoylacetonitrile (25 g), cyclohexanone (25 g) and 75% polyphosphoric acid (250 g) is stirred at 50° C. for 30 minutes and further at 110° C. for 1.5 hour. After cooling, the reaction mixture is poured into ice-water and thereto is added diethyl ether (300 ml). The mixture is stirred and the precipitated crystals are collected by filtration. The crystals are recrystallized from N,N-dimethylformamide-ethanol to give the desired compound (27 g), m.p. 285°-288° C.
