Abstract
NEW MATERIAL:A quinoline derivative shown by the formula I (R1 and R2 are both H, or one is OH or 1W5C lower alkoxy and the other is H; R3 is H, salt forming residue, or ester forming residue).
EXAMPLE: 4,5-Dihydroxy-3-quinolinecarboxylic acid ethyl ester.
USE: An intermediate for penicillin or a cephalosporin derivative.
PROCESS: A compound shown by the formula II is reacted with a compound shown by the formula III (E is ester forming residue) in a solvent to give a compound shown by the formula IV, which is reacted with a mixture of polyphosphoric acid and phosphorus oxychloride, to give a compound shown by the formula I wherein R3 is H.
