실험 절차

To a solution of 2-methyl-2-(4-nitro-1H-pyrazol-1-yl)propanoic acid (1.2 g) obtained in Step A of Example 109 in N,N-dimethylformamide (10 mL) were added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (1.3 g) and 1-hydroxybenzotriazole ammonia salt (1.4 g), and the mixture was stirred overnight at room temperature. To the reaction mixture was added saturated aqueous sodium hydrogen carbonate solution, and the mixture was extracted with ethyl acetate. The obtained organic layer was washed successively with water and saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (NH, ethyl acetate) to give the title compound (1.0 g).
