실험 절차

Sodium hydride (60%, oily, 60.0 mg) was added to a solution of ethyl 3-[3-ethoxy-1-(4-hydroxybenzyl)-1H-pyrazol-4-yl]propionate (478 mg) and 1-chloromethyl-1H-benzotriazole (251 mg) in N,N-dimethylformamide (10 ml) at, 0° C., and the mixture was stirred at room temperature for 1 hour. The reaction mixture was poured into water, and extracted with ethyl acetate. The ethyl acetate layer was washed with saturated aqueous sodium chloride solution, dried (MgSO4), and concentrated. The residue was subjected to silica gel column chromatography to obtain ethyl 3-[1-[4-(1H-benzotriazol-1-ylmethoxy)benzyl]-3-ethoxy-1H-pyrazol-4-yl]propionate (652 mg, yield: 97%) as a colorless oily substance from the fraction eluted with ethyl acetate-hexane (1:1, volume ratio).
