Reaction Steps

A solution containing 1.1 g of pyridine-4-carboxaldehyde and 1.0 g of 2,4-pentanedione in 10 ml of N,N-dimethylformamide was saturated with hydrogen chloride gas at 20° C. The solution was stirred for 1 h at 20° C. and then for 2 h at 80° C. The solvent was evaporated in vacuo and the residue was crystallized from ethanol. Yield 0.17 g, mp 175°-186° C.
