Abstract Ethyl 3-furfuryl-4-oxo-3, 4-dihydroquinazoline-2-carboxylate extremely readily undergoes hydrolysis in acid, alkaline, or neutral medium with formation of 2-(2-ethoxy-1, 2- dioxoethylamino)-N-furfurylbenzamide. The reaction of ethyl 3-furfuryl-4-oxo-3, 4- dihydroquinazoline-2-carboxylate with phenylmagnesium bromide yields N-furfuryl-2-(2- hydroxy-2, 2-diphenyl-1-oxoethylamino) benzamide as a result of hydrolytic cleavage of ...
