PROCEDURE

实验过程

A solution of 2-{2-[7-chloro-3-(3,5-dimethylphenyl)-2-oxo-6-(3-pyridin-4-yl-ureido)-1,2-dihydroquinolin-4-yloxy]-ethyl}-piperidine-1-carboxylic acid benzyl ester in 3 mL of a 30% solution of hydrobromic acid in acetic acid was stirred at room temperature for 3 hours then concentrated in vacuo. The residue was treated with saturated sodium bicarbonate and then extracted with ethyl acetate. Purification of the concentrate by flash chromatography on silica gel (methylene chloride:methanol:ammonium hydroxide, 96:3:1) gave the title compound.
