実験手順

A stirred solution of 1-(6-hydroxy-1H-benzoimidazol-2-yl)-3-(2-methoxy-ethyl)-urea (31 mg, example 82) and benzoic acid 4-chlorosulfonyl-phenyl ester (37 mg) in acetone (0.6 ml) was treated with triethylamine (33 μl). After stirring at ambient temperature for 4 hours, the reaction mixture was evaporated. The residue was filtered and the filtrate evaporated. The residue was directly purified by LCMS triggered purification to give benzoic acid 4-{2-[3-(2-methoxy-ethyl)-ureido]-1H-benzoimidazol-5-yloxysulfonyl}-phenyl ester (7.2 mg) as a off-white solid Mass spectrum: 511 [M+H]+; retention time=9.90 minutes.
