Abstract
NEW MATERIAL:A pyridazine derivative of formula I [R1 is H, lower alkyl, acyl; R2 is H, lower alkyl; R3,4 are H, lower alkyl, amino, etc.; or R3 and R4 may form together with adjascent N atom a heterocyclic ring (which may contain a group II (R5 is lower alkyl, aralkyl, etc.), -O-, -S-.); n is 1, 2; X is O, H2].
EXAMPLE: 3-Ethoxycarbonylhydrazine-6-(1-methyl-2-oxo-1,2,3,4-tetrahydroquinolin- 6-yl)-4,5-dihydro-5-methlpyridazine.
USE: Medicine for circulatory organs having hypotensive, vasodilating and cerebral blood flow accelerating effects.
PROCESS: The compound I is prepared by reacting a compound III (novel compound) with a compound IV without solvent or in a solvent such as water, THF, etc., with or without heating.
