Summary:A method for producing (R)-5-(3,4-difluorophenyl)-5-[(3-methyl-2-oxopyridin-1(2H)-y l)methyl]imidazolidine-2,4-dione, the method comprising, (a) a step for isolating an isomer represented by formula (2) from a mixture of isomers represented by formula (1), and (b) a step for obtaining (R)-5-(3,4-difluorophenyl)-5-[(3-methyl-2-oxopyridin-1(2H)-yl)methyl]imi dazolidine-2,4-dione by removing the menthyloxycarbonyl group from the compound represe nted by formula (2), which was isolated in step (a).
