Procedure

10-amino-6,7-dihydro-5-methyl-1,7-dioxo-1H,5H-benzo[ij]quinolizine-2-carboxylic acid (0.02 mole) and acetic anhydride (50 ml.) are stirred and heated on a steam bath for 3 hours. After cooling, the solid precipitate is separated by filtration to give 10-acetamido-6,7-dihydro-5-methyl-1,7-dioxo-1H,5H-benzo[ij]quinolizine-2-carboxylic acid. This product is reduced using sodium borohydride to provide 10-acetamido-6,7-hydroxy-5-methyl-1-oxo-1H,5H-benzo[ij]quinolizine-2-carboxylic acid.
