    摘要: Disclosed is a process for producing A-form crystals of 2-(3-cyano-4-isobutyloxyphenyl)-4-methyl-5-thiazolecarboxylic acid, comprising: a step of dissolving by heating 2-(3-cyano-4-isobutyloxyphenyl)-4-methyl-5-thiazolecarboxylic acid in one or a plurality of solvents as a good solvent, selected from the group consisting of 1-propanol, 2-propanol, ethanol, and acetone; a step of cooling the solution; and a step of adding to the solution a hydrocarbon solvent as a poor solvent.
