Procedure
The procedure described in Example 1 was repeated, except that dihydropyran (1.46 ml) and ethyl m-aminobenzoate (2.13 g) were successively reacted with (S)-2-(4-chlorobenzenesulfonylamino)-3-hydroxypropanoic acid (3 g) to obtain (S)-2-(4-chlorobenzenesulfonylamino)-N-(3-ethoxycarbonylphenyl)-3-(tetrahydropyran-2-yloxy)propanamide (2.3 g).
