Procedure

4-Amino-6-methylpyrimidine-5-carboxaldehyde is then condensed with 2,6-dichlorophenylacetonitrile. The crude product is isolated by concentrating the reaction mixture to dryness and partitioning the residue between chloroform and water. Drying and concentration of the organic layer gives a residue which is chromatographed on silica gel. The product is eluted with 1/99 mixture of methanol/chloroform and recrystallized from ethanol to give pure 6-(2,6-dichlorophenyl)-4-methylpyrido[2,3-d]pyrimidin-7-amine, mp 280°-282° C.
