실험 절차

To a solution of 1-(4-fluorophenyl)-5-(3-(trifluoromethoxy)phenyl)-1H-pyrazol-3-ylamine (90 mg) in N,N-dimethylformamide (0.9 ml) were added (3R,4R)-4-methyl-5-oxopyrrolidine-3-carboxylic acid (50 mg) prepared in Preparation 1, HOBt.H2O (61 mg) and WSC.HCl (77 mg), and the mixture was stirred at room temperature for 2 hours. To this mixture were added water and a saturated aqueous solution of sodium hydrogen carbonate, and the mixture was extracted with ethyl acetate. The separated organic layer was washed with 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: chloroform/methanol=10/1) to give the titled compound (80 mg).
