Urea and its methyl derivatives are convenient reagents in a new single-stage method for the synthesis of compounds of the 1,4-dihydropyridine and pyridine series.Like benzaldehyde, under the discovered conditions benzyl alcohol gives hydrogenated 9-phenyltetramethylacridine-1,8-dione in reaction with urea and dimedone.
