Reaktionsschritte
The procedure described in Example 15 was repeated, except that (RS)-2-(benzyloxycarbonylamino)-N-(4-(ethoxycarbonylmethyl)phenyl)-3-(tetrahydropyran-2-yloxy) propanamide (1.0 g) was hydrogenolyzed in the presence of 10% Pd-C, and then, reacted with 4-methylbenzenesulfonyl chloride (778 mg) to obtain (RS)-N-(4-(ethoxycarbonylmethyl)phenyl)-2-(4-methylbenzenesulfonylamino)-3-(tetrahydropyran-2-yloxy)propanamide (540 mg).
