Procedure
A mixture containing 1.0 g of ethyl 5-ethoxy-2-(4-methyl-1-piperazinyl)pyrido[2,3-d]pyrimidine-6-carboxylate and 5.0 ml of ethyl iodide was heated to reflux for one hour. After ethyl iodide was recovered by distillation, the resulting solid was crystallized from water to give 0.69 g of the product, m.p. 146° - 147°C.
