Vorschrift

The procedure described in Example 177 was repeated, except that (RS)-2-(4-chlorobenzenesulfonylamino)octanoic acid (1 g) and ethyl 4-aminophenylacetate hydrochloride (581 mg) were condensed in chloroform (30 ml) in the presence of triethylamine (1.66 ml) and 1-methyl-2-chloropyridinium iodide (918 mg) to obtain (RS)-2-(4-chlorobenzenesulfonylamino)-N-(4-(ethoxycarbonylmethyl)phenyl)octanamide (350 mg).
