Procedure
To 2 g. (0.0056 mole) of 5-chloro-7,8-dihydro-8-ethyl-7-oxo-2-phenylpyrido[2,3-d]pyrimidine-6-carboxylic acid ethyl ester (prepared by the method of the first paragraph of Example 3) was added 20 ml. of 2-aminoethanol and this mixture was heated at reflux for 1.5 hours. The reaction mixture was chilled in ice and the product collected on a filter and recrystallized from ethanol to give 1.7 g. of product--m.p. 250°-253° C.
