Participants

Reaction Steps

A solution of 1.0 g of sodium 8-bromo-6,7-dihydro-9-fluoro-5-methyl-1-oxo-1H,5H-benzo[ij]quinolizine-2-carboxylate in 30 ml of warm water was stirred with 1 g magnesium sulfate in 20 ml of water and warmed on a steam bath for 15 minutes. Cooling and filtration provided magnesium 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)2Mg.H2O; %C, 47.1; %H, 3.0; %N, 3.9; Found: %C, 46.9; %H, 3.2; %N, 3.9.
