Procedure
3-Ethyl-1-(2-((4-(morpholin-4-yl)phenyl)amino)pyrimidin-4-yl)-2-oxopyrrolidine-3-carbonitrile (200 mg) obtained in Example 2 was resolved by SFC (column: CHIRALCEL OJH, 20 mmID×250 mmL, manufactured by Daicel Chemical Industries, mobile phase: carbon dioxide/methanol/acetonitrile=660/170/170), and the compound having a shorter retention time was recrystallized (hexane/ethyl acetate) to give the title compound (47 mg).
