Reaction Steps

To a solution of 1-(4-chlorophenyl)-5-[3-fluoro-5-((R)-2,2,2-trifluoro-1-methylethoxymethyl)phenyl]-1H-pyrazol-3-ylamine (about 0.110 mol) prepared in the previous step in N,N-dimethylacetamide (0.5 ml) were sequentially added (S)-5-oxopyrrolidine-3-carboxylic acid (17 mg) prepared in Preparation 14 and WSC.HCl (32 mg) at room temperature, and the mixture was stirred for 0.5 hours. To this reaction mixture was added water, and then the precipitated solid was collected by filtration. The resulting solid was purified by silica gel thin-layer chromatography (eluent: chloroform/methanol=9/1) to give the titled compound (18 mg).
