Procedure

A stirred mixture of 5.9 g. (0.02 mole) of 1-ethyl-1,2-dihydro-4-chloro-7-methyl-2-oxo-1,8-naphthyridine-3-carboxylic acid ethyl ester, 1.4 g. (0.02 mole) of pyrrolidine and 2.12 g. (0.02 mole) of sodium carbonate was heated under reflux in 50 ml. of ethanol for 3 hours. The mixture was filtered and the filtrate was diluted with water to the cloudy point. The precipitate which formed was collected, air dried and was recrystallized from heptane to give 3.3 g. of the title compound, m.p. 113°-115° C.
