Abstract

NEW MATERIAL:A compound of formula I (one of R1 and R2 is lower alkyl, and the other is H or lower alkyl; R3 is H or lower alkyl; X is H, halogen, or lower alkyl).
EXAMPLE: 6-( 6-Hydrazino-4,5-dihydro-4-methyl-3-pyridazinyl )-1,2,3,4-tetrahydro-1,4,4-trimethylquinolin-2-one hydrochloride.
USE: Hypotensive agents and antithrombogenetic agents.
PROCESS: The compound of formula I is prepared by reacting (A) a compound of formula II, III (R4 is lower alkyl or aralkyl) or IV (R5, R6 are H or lower alkyl) or its acid addition salt with (B) hydrazine or its hydrate in an inert solvent or in the absence of solvent at a temperature between room temperature and the refluxing temperature. The compounds of formulas IIWIV are also novel.
