Reaction Steps

To a solution of 2.4 g. (7.5 mmole) of 1-(4-chlorophenyl)-4(1H)-pyridinone hydrazone fluorosulfonate, prepared by the process set forth in Example 2, in 35 ml. ethanol and 30 ml. water was added a solution of 1.27 g. (9 mmole) of p-chlorobenzaldehyde in 5 ml. ethanol. After heating the reaction mixture on the steam bath for 3 minutes, the mixture was concentrated to remove most of the ethanol, cooled and the product collected by filtration. Yield 3.1 g. (94%), recrystallized from EtOH-H2O, m.p. 252°-253° C. The elemental analyses for C, H, N and Cl were within ±0.4% of the theoretical values.
