Reaction Steps

Solutions of 1.7 g sodium 8-bromo-6,7-dihydro-9-fluoro-5-methyl-1-oxo-1H,5H-benzo[ij]quinolizine-2-carboxylate in 40 ml warm water and 2 g calcium chloride in 20 ml warm water were stirred together, heated on a steam bath for 15 minutes and cooled about 16 hours. The product was separated by filtration, washed with water and dried to provide light pink calcium 8-bromo-6,7-dihydro-9-fluoro-5-methyl-1-oxo-1H,5H-benzo[ij]quinolizine-2-carboxylate hydrate, m.p. >300° C. Analysis: Calculated for (C14H10BrFNO3)2Ca.1/2H2O: %C, 45.7; %H, 3.0; %N, 3.8; Found: %C, 45.7; %H, 3.2; %N, 3.8. The structural assignment was confirmed by infrared spectral analysis.
