Procedure

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.
