The present invention provides a process for producing a compound of the formula (1) wherein X represents a hydrogen atom, etc., and Y represents a hydrogen atom, etc., which comprises step 1 of reacting a compound of the formula (2) and a compound of the formula (3) in the presence of a Lewis acid wherein R represents a hydrogen atom, etc., to obtain an adduct, and step 2 of reacting the adduct obtained in the step 1 and hydrazine to obtain the compound of the formula (1). 

Process for producing pyridazinone compound and production intermediates thereof

A compound represented by formula (2) wherein X represents a hydrogen atom, a fluorine atom, a chlorine atom or a bromine atom, and Y represents a hydrogen atom, a fluorine atom, a chlorine atom or a bromine atom, is reacted with a brominating agent and an alkanol having 1 to 6 carbon atoms in the presence of a base to obtain a compound represented by formula (3) wherein R represents a C1 to C6 alkyl group, and X and Y represent the same meaning as described above, and then the compound represented by the formula (3) is reacted with hydrazine, whereby a compound represented by formula (1) wherein X and Y represent the same meaning as described above, which is useful as a production intermediate of a fungicide, can be obtained.

Method of manufacturing pyridazinone compound
