| abstract | NEW MATERIAL: A compd. represented by formula I (wherein R is H or 1-3C alkyl) and its acid adducts. n EXAMPLE: 6-fluoro-4-hydroxytetrahydroquinaldine hydrochloride. n USE: An intermediate for producing 6,7-dihydro-9-fluoro-5-methyl1-oxo-1H,5H- benzo[ij] quinolidine-2-carboxylic acid (represented by formula II). Yield is enhanced by using this intermediate and advantages such as the conservation of the number of reaction reagents from an aspect of production, the number of work processes and the reduction of dfficulty are shown. n PROCESS: Crotonaldehyde or a crotonaldehyde precursor such as acetaldehyde or para-aldehyde forming croton aldehyde under an acidic reaction condition and 4-fluoroanilln are reacted in the presence of dilute aq. acid such as hydrochloric acid to obtain the compd. represented by formula I. n COPYRIGHT: (C)1990,JPO |
