The condensation of ethyl acetoacetate with formaldehyde and primary amines in methanol at 65A degrees C (Mannich reaction) gave up to 92% of hexahydropyrimidine derivatives containing ester and acetyl groups. Analogous reaction with aminopyridines stopped at the stage of formation of linear condensation products.
