Procedure

To a solution of 1-(4-chlorophenyl)-5-[3-((R)-2,2,2-trifluoro-1-methylethoxymethyl)phenyl]-1H-pyrazol-3-ylamine (about 0.125 mmol) prepared in the previous step in N,N-dimethylformamide (1 ml) were sequentially added (S)-5-oxopyrrolidine-3-carboxylic acid prepared according to the same procedures as preparation 14 (18 mg) and WSC.HCl (29 mg) at room temperature, and the mixture was stirred for 3 hours. To this reaction mixture was added water, and the mixture was extracted with ethyl acetate. The resulting organic layer was concentrated under reduced pressure, the resulting residue was purified by silica gel thin-layer chromatography (eluent: chloroform/methanol=10/1). To the resulting solid were added water and a small amount of methanol, 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 (33 mg).
