実験手順
Diethyl (2-benzylamino-5-pyridylaminomethylene)malonate (2.23 g) was added to diphenyl ether (10 mL) preheated to 230° C. Heating was continued for 0.5 h, the reaction flask removed from the oil bath, and the mixture allowed to cool to ambient temperature. The product was triturated with 1:1 ether:hexanes, collected, rinsed with ether, and dried to give 1.47 9 of ethyl 6-benzylamino-4-oxo-1,4-dihydro-1,5-naphthyridine-3-carboxylate as a brown solid.
