Procedure

2.0 g of 6-(4-(2-(4-chlorobenzenesulphonylamino)ethyl)-phenyl)-6-(3-pyridyl)hex-5-enoic acid are stirred overnight in 10 ml of 4N sodium hydroxide solution, 100 ml of methylene chloride, 80 mg of benzyl trimethylammonium chloride and 0.85 g of methyl iodide. Then the organic phase is separated off and the aqueous phase is acidified to pH 5. The product precipitated is separated off and taken up in methylene chloride, dried and evaporated down. Finally, the residue is chromatographed with ethylene chloride/methanol (97:3) over a silica gel column.
