Abstract
A convenient method has been proposed for the synthesis of 2-(4,7-dioxopyrido[2,3-d]pyrimidin-6-yl)acetanilides and 2-(2,4,7-trioxopyrido[2,3-d]pyrimidin-6-yl)acetanilides via reaction of N-arylitaconimides with 6-aminopyrimidin-4(3H)-ones and 6-aminopyrimidine-2,4(1H,3H)-diones, respectively, in boiling acetic acid.Keywords
