Abstract

NEW MATERIAL:A pyridazinone derivative expressed by formula I (R1, R2 and R3 are H, halogen, lower alkyl or lower alkyloxy; R4 and R5 are H or lower alkyl; X is S or -CH2-; m is an integer 1W3; n is 0 or an integer 1W3).
EXAMPLE: N-Cyano-N'-[ 3-[ 6-( 4-chlorophenyl )-3-oxo-2-pyridazinyl ]propyl ]-N'- methylguanidine.
USE: A medicine, useful as a remedy and a preventing agent aginst peptic ulcers, e.g. gastric hyperacidity, gastric ulcer and duodenal ulcer, and capable of exhibiting the activity of inhibiting the gastric juice secretion and inhibiting the development of a experimental ulcers, e.g. the aspirin, stress or Shay ulcer, with prolonged action, weak toxicity and improved chemical resistance.
PROCESS: An amine derivative expressed by formula II is reacted with dimethyl cyanodithioimidocarbonate to give an isothiourea derivative expressed by formula III, which is then reacted with an amine derivative expressed by formula IV in an inert solvent at room temperature or under heating for several hours to afford the compound expressed by formula I.
