Procedure

The procedure described in Example 15 was repeated, except that (RS)-2-(benzyloxycarbonylamino)-N-(4-(ethoxycarbonylmethyl)phenyl)-3-(tetrahydropyran-2-yloxy)propanamide (0.68 g) was hydrogenolyzed in the presence of 10% Pd-C, and then, reacted with 4-methoxybenzenesulfonyl chloride (575 mg) to obtain (RS)-N-(4-(ethoxycarbonylmethyl)phenyl)-2-(4-methoxybenzenesulfonylamino)-3-(tetrahydropyran-2-yloxy)propanamide (3 19 mg).
