Participants

Reaction Steps

A mixture of 3-[4-(2-ethoxycarbonylethyl)-3-phenyl-1H-pyrazol-1-ylmethyl]benzoic acid (700 mg), 4-trifluoromethylbenzylamine (390 mg), 1-hydroxybenzotriazole monohydrate (340 mg), WSC (430 mg), and N,N-dimethylformamide (30 ml) was stirred at room temperature for 18 hours. The reaction mixture was poured into water, which was extracted with ethyl acetate. The ethyl acetate layer was washed with water, dried (MgSO4), and concentrated. The residue was subjected to silica gel column chromatography, and ethyl 3-[3-phenyl-1-[3-(4-trifluoromethylbenzylaminocarbonyl)benzyl]-1H-pyrazol-4-yl]propionate (900 mg, yield: 91%) was obtained as an oily substance from the fraction eluted with acetone-hexane (1:2, volume ratio).
