    Abstract: NEW MATERIAL:The 4-oximino-1,2,3,4-tetrahydroquinoline derivative of formula (R is alkyl; X is F, Cl or Br). EXAMPLE:6-Chloro-4-oximino-1-methoxycarbonyl-1,2,3,4-tetrahydroquinoline. USE:Medicine. It has strong antihydropic and diuretic activities, and extremely low adverse effect to the digestive organs. PROCESS:The compound of formulaIis prepared e.g. by (1) heating a p-halogen- substituted aniline and an acrylic acid ester in a solvent, (2) hydrolyzing the resultant compound and heating in the presence of a dehydrating agent to afford a 6-halogen-substituted 4-oxo-1,2,3,4-tetrahydroquinoline, (3) reacting the compound with various chloroformate which can condense the compound to effect the N-alkoxy-carbonylation of the product, and (4) heating the resultant compound in a mixed solvent of pyridine and alcohol in the presence of hydroxylamine hydrochloride.

    Abstract: NEW MATERIAL:A 4-hydroxyimino-1,2,3,4-tetrahydroquinoline derivative expressed by the formula (R is H, alkyl, halogen substituted lower alkyl, phenyl substituted lower alkyl, phenylalkenyl, aromatic group containing nitrogen or alkyl or phenyl substituted amino). EXAMPLE:6-Chloro-4-hydroxyimino-1-formyl-1,2,3,4-tetrahydroquinoline. USE:An antihydrophic and a diuretic agent with almost no gastric disorder. PROCESS:p-Chloroaniline is heated with an acrylic ester in a solvent, e.g. benzene, or if desired with a base, e.g. sodium hydride, at room temperature or under heating to carry out the Michael addition reaction to obtain a 3-(p-chlorophenylamino) propionic ester. The resultant ester is hydrolyzed and then heated in the presence of a dehydrating agent to afford the compound expressed by the formula.
