| titleOfInvention | Pyridazinone derivative or salts thereof |
| abstract | NEW MATERIAL:The pyridazinone derivative of formula I (R 1 and R 3 are H or 1W5C alkyl; R 2 is H, 1W5C alkyl, 1W5C alkoxy or 1W5C alkylthio; R 4 , R 5 and R 6 are H, OH or 1W5C alkoxy; two of R 4 , R 5 and R 6 may together form -O-CH 2 -O- or -O-CH 2 -CH 2 -O-; m is 0W4; n is 1W4; dotted line shows that the bond between the 4- and 5-carbon atoms is single bond or double bond) or its salt. n USE: Useful as a cardiotonic agent. It can be administered orally or parenterally. It has long-acting effect. n PREPARATION: The compound of formula I can be produced according to the reaction formula, by the amide bond formation reaction of a carboxylic acid of formula II with an amine of formula III. The formation of amide bond can be carried out e.g. by reacting the compound of formula II with an alkyl halocarboxylate and reacting the resultant mixed acid anhydride with the amine of formula III. n COPYRIGHT: (C)1988,JPO&Japio |
