Synthesis of derivatives of 1-(2-carboxyethyl)-(1H,3H)-quinazoline-2,4-dione

The action of alkylating agents on 1-(2-carboxyethyl)-(1H,3H)-quinazoline-2,4-dione was utilized to synthesize corresponding esters. The hydrolysis and hydrazinolysis of the last were accomplished. Polyphosphoric acid effected the conversion of 1-(2-carboxyethyl)quinazolinedione to 1,3,7-trioxopyrido1,2,3-k,j]quinazoline.Kaunas Technological University, Kaunas LT 3028.
