Reaction Conditions

Reaction Steps

A mixture of 1.63 g of 2-tetrahydrofurfurylamino-5-nitrobenzophenone, 3.0 g of ethyl carbamate and 0.2 g of zinc chloride was heated at 190° C. (oil bath temperature) for 2 hours. After cooling, the reaction mixture was dissolved in chloroform and the insoluble material was filtered off. The chloroform solution was washed successively with dilute hydrochloric acid and water, and dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure and the residue was washed with ether. The insoluble product was collected by filtration and dried to give 1-tetrahydrofurfuryl-4-phenyl-6-nitro-2(1H)-quinazolinone, m.p. 150°-152° C.
