| titleOfInvention | Process for preparing pyridazin-3-on derivatives |
| abstract | It is possible to prepare pyridazin-3-one derivatives of the general formula (1) in high yield and high purity by the ring closure reaction of carboxylic acid derivatives of the general formula (2) or salts thereof in the presence of a nitrogen-containing aromatic compound and a boron compound:n n n [Formula 1]n n n n n n n n [Wherein R 2 is a hydrogen atom or a C 1 -C 3 alkyl group, R 3 is a hydrogen or a C 1 -C 3 alkyl group, and Q may be optionally substituted with a phenyl group]n n n [Formula 2]n n n n n n n n [Wherein, R 2 , R 3 and Q are as defined above. |
