PROCEDURE
实验过程
To a solution of 15 mg 4-[(S)-2-({5-[2-((S)-2-Cyclobutylcarbamoyl-pyrrolidin-1-yl)-2-oxo-ethoxy]-1-phenyl-1H-pyrazole-3-carbonyl}-amino)-3-(2,2-dimethyl-[1,3]dioxolan-4-yl)-propionyl]-piperazine-1-carboxylic acid ethyl ester in 5 ml MeOH were added 5 mg pyridinium p-toluenesulfonate and the solution was stirred for 2 h before being concentrated in vacuo. The residue thus obtained was purified by preparative HPLC (C18 reverse phase column, elution with a water/MeCN gradient with 0.1% TFA). The fractions containing the product were lyophilized to yield the pure product.
