Versuchsvorschrift

The procedure described in Example 1 was repeated, except that dihydropyran (1.93 ml) and methyl 7-aminoheptanate hydrochloride (1.679 g) were successively reacted with (RS)-2-(4-chlorobenzenesulfonylamino)-3-hydroxypropanoic acid (2 g) to obtain (RS)-2-(4-chlorobenzenesulfonylamino)-N-(6-methoxycarbonylhexyl)-3-(tetrahydropyran-2-yloxy)propanamide (1. 497 g).
