반응 단계
To a solution of 400 mg 1-[5-(5-Chloro-thiophen-2-yl)-isoxazol-3-ylmethyl]-5-furan-2-yl-1H-pyrazole-3-carboxylic acid ethyl ester in 5 ml THF and 1 ml water, 1 ml aqueous NaOH (1M) were added and the mixture was stirred for 16 h at RT. Then the solution was acidified to pH 3 with half concentrated hydrochloric acid to precipitate the pure product, which was collected by filtration. Yield: 360 mg.
