METHOD FOR PRODUCING MALEATE USING WET CRYSTAL

[Problem] To efficiently (without carrying out column purification) provide a high-purity maleate having excellent storage stability, solubility, crystallinity and ease of handling according to the present invention. [Solution] This method for producing the maleate represented by formula (1) includes obtaining the compound represented by formula (2) by reacting the compound represented by formula (3) with the compound represented by formula (4) in the presence of a salt, precipitating crystals of the compound represented by formula (2) by mixing the obtained compound represented by formula (2) with acetone and water, and obtaining the maleate represented by formula (1) by adding maleic acid to an acetone solution of the compound represented by formula (2), prepared by dissolving the crystals of the obtained compound represented by formula (2) in acetone.
