Procedure

In analogy to the procedure described in example 50k), crude rac-3-(2,3-dihydroxy-propoxy)-5-methoxy-N-piperidin-4-yl-benzamide trifluoroacetate (example 175b) was reacted with 3,5-diethoxy-4-fluoro-benzaldehyde (example 50 g), sodium cyanoborohydride, N-ethyl-diisopropylamine and acetic acid in ethanol at 50° C. to yield the title compound as colorless amorphous solid. MS: 521.4 (MH+).
