Versuchsvorschrift
The procedure described in Example 1 was repeated, except that dihydropyran (2.7 g) and ethyl p-aminobenzoate (2.13 g) were successively reacted with (RS)-2-(4-chlorobenzenesulfonylamino)-3-hydroxypropanoic acid (3 g) to obtain (RS)-2-(4-chlorobenzenesulfonylamino)-N-(4-ethoxycarbonylphenyl)-3-(tetrahydropyran-2-yloxy)propanamide (1.962 g).
