To a solution of 1-(4-fluorobenzoyl)-3-isopropyl-2-oxopyrrolidine-3-carbonitrile (280 mg) obtained in Step A in tetrahydrofuran (3 mL) was added n-octylamine (180 μL), and the mixture was stirred overnight at room temperature. To the reaction mixture was added n-octylamine (168 μL) at room temperature, and the mixture was stirred at 50° C. for 5 hr. The reaction mixture was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (hexane/ethyl acetate) to give the title compound (120 mg).
