Reaction Steps

The procedure described in Example 15 was repeated, except that (RS)-2-(benzyloxycarbonylamino)-N-(4-(ethoxycarbonylmethyl)phenyl)-3-(tetrahydropyran-2-yloxy)propanamide (500 mg) was hydrogenolyzed in the presence of 10% Pd-C, and then, reacted with 4-chloro-3-nitrobenzenesulfonyl chloride (524 mg) to obtain (RS)-2-(4-chloro-3-nitrobenzenesulfonylamino)-N-(4-(ethoxycarbonylmethyl) phenyl)-3-(tetrahydropyran-2-yloxy)propanamide (198.2 mg).
