Participants

Reaction Steps

To a solution of 0.0997 g of sodium hydroxide in 40 ml of water was added 0.8 g of 2,3-dihydro-3-methyl-7-oxo-10-phenyl-7H-pyrido[1,2,3-de]-1,4-benzoxazine-6-carboxylic acid. The mixture was heated briefly until the carboxylic acid dissolved. The solution was then filtered and the filtrate obtained was then evaporated to provide a residue. The residue was dissolved in 50 ml of water, the solution filtered and the filtrate was lyophilized to provide light tan solid, sodium 2,3-dihydro-3-methyl-7-oxo-10-phenyl-7H-pyrido[1,2,3-de]-1,4-benzoxazine-6-carboxylate, m.p. 236° C. (dec.). Analysis: Calculated for C19H14NNaO4.1.5H2O: %C, 61.6; %H, 4.6; %N, 3.8; Found: %C, 61.4; %H, 4.3; %N, 3.6. The structural assignment was confirmed by infrared spectral analysis.
