Procedure

A stirred mixture of 7.41 g. (0.03 mole) of 4-chloro-1-ethyl-1,2-dihydro-7-methyl-2-oxo-1,8-naphthyridine-3-carbonitrile, 2.13 g. (0.03 mole) of pyrrolidine and 3.18 g. (0.03 mole) of sodium carbonate in 100 ml. of ethanol was heated under reflux for 1 hour. The mixture was filtered and the filter cake was triturated with 200 ml. of water. The insoluble material was collected, air dried and was recrystallized from 2-ethoxyethanol to give 7.4 g. of the title product, m.p. 211°-213° C.
