Reaction Steps

To a solution of 1-(2-chloropyrimidin-4-yl)-3-ethyl-2-oxopyrrolidine-3-carbonitrile (20 mg) obtained in Step A of Example 2 and 4-(aminomethyl)benzonitrile hydrochloride (27 mg) in N-methylpyrrolidone (2 mL) was added diisopropylethylamine (0.028 mL), and the mixture was stirred at 60° C. for 3 hr. To the reaction mixture were added ethyl acetate (3 mL) and water (1 mL), and the mixture was stirred for 5 min. The organic layer was filtered through Top-Phase Separation Filter Tube, and the solvent was evaporated at 60° C. The residue was purified by HPLC (C18, mobile phase: acetonitrile/10 mM aqueous ammonium hydrogen carbonate solution), and dried at 60° C. to give the title compound.
