Reaction Steps

The procedure described in Example 177 was repeated, except that (RS)-2-(4-chlorobenzenesulfonylamino)-4-ethylthiobutanoic acid (1 g) and ethyl 4-aminophenylacetate hydrochloride (574.6 mg) were condensed in chloroform (30 ml) in the presence of triethylamine (1.64 ml) and 1-methyl-2-chloropyridinium iodide (907.5 mg) to obtain (RS)-2-(4-chlorobenzenesulfonylamino)-N-(4-(ethoxycarbonylmethyl)phenyl)-4-ethylthiobutanamide (113 mg).
