titleOfInvention | Production method of pyridazinone compounds |
abstract | A method of producing a compound represented by formula (I) or formula (I '): ** Formula ** in which R1 and R2 are each independently a hydrogen atom or a substituent (excluding a benzyloxy group) , ring A is an optionally substituted aromatic ring, and R7 is an optionally substituted hydrocarbon group or an optionally substituted heterocyclic group, as long as a compound in which R1 and R2 are the same groups, or one of their mixtures is excluded or one of its salts, comprising step (1): a reaction step of a compound represented by formula (II): ** Formula ** in which each symbol is as defined above, or one of its salts , with a compound represented by the formula (IIIa): ** Formula ** in which R3a, R4a, R5a and R6a are each independently an optionally substituted hydrocarbon group, or one of its salts, to give a compound represented by the formula (IV) or formula (IV '): ** Formula a ** in which each symbol is as defined above, or one of its mixtures or one of its salts; step (2): a reaction step of the compound represented by the formula (IV) or the formula (IV ') or one of its mixtures or one of its salts with a compound represented by the formula (IIIb): ** Formula * * wherein R3b, R4b, R5b and R6b are each independently an optionally substituted hydrocarbon group, or one of its salts, to give a compound represented by the formula (Vb) or the formula (V'b): ** Formula ** in which each symbol is as defined above, or one of its mixtures or one of its salts; and step (3): a reaction step of the compound represented by the formula (Vb) or the formula (V'b) or one of its mixtures or one of its salts, with a compound represented by the formula (VI): * * Formula ** R7NH NH2 (VI) in which each symbol is as defined above, or one of its salts. |
