2-Dimethylaminomethylene-3-oxo-N-phenylbutyramide reacts with malononitrile to afford the pent-2-enedioic acid 1-amide 5-phenylamide derivative , which could be cyclized to give the 6-methylpyridone derivative . Compound reacts with cyanoacetamide to afford the same pyridone and with cyanothioacetamide to afford the analogous pyridinethione . Compound reacts with DMAD to afford the pyridine derivative
