Procedure

To a solution of 5-(3-butylphenyl)-1-phenyl-1H-pyrazol-3-ylamine (40 mg) in N,N-dimethylformamide (0.4 ml) were sequentially added (R)-2-oxoimidazolidine-4-carboxylic acid (21 mg) prepared by the same procedures as Preparation 20, HATU (63 mg), diisopropylethylamine (29 μL) at room temperature, and the mixture was stirred for 2 hours. To this reaction mixture was added water, and the mixture was extracted with ethyl acetate. The resulting organic layer was washed with water and a saturated aqueous solution of sodium chloride, dried over anhydrous sodium sulfate, and then concentrated under reduced pressure. The resulting residue was purified by silica gel thin-layer chromatography (eluent: n-hexane/acetone=1/5). To the resulting solid was added diisopropyl ether, and the mixture was stirred. A solid was collected from this suspension by filtration, and was dried under reduced pressure to give the titled compound (12 mg).
