Procedure
2,6-Dichlorophenylacetonitrile 8.1 g and 4-amino-2-methylpyrimidine-5-carboxaldehyde 6.9 g is added to a solution of 0.4 g of sodium metal in 60 ml of anhydrous ethanol. This mixture is heated at reflux for 3 hours. Upon cooling, the crude product precipitates and is collected by filtration. The solid is recrystallized from ethanol, with charcoal treatment, to give 5.5 g of 6-(2,6-dichlorophenyl)-2-methylpyrido[2,3-d]pyrimidin-7-amine, mp 287°-289° C., which may occlude varying amounts of water, depending on the drying conditions.
