Reaction Steps

In analogy to the procedure described in example 50k), 2-methyl-2-[4-(piperidin-4-ylcarbamoyl)-phenyl]-propionic acid methyl ester (example 60e) was reacted with 3,5-diethoxy-4-pyrrol-1-yl-benzaldehyde (example 40b), sodium cyanoborohydride, N-ethyl-diisopropylamine and acetic acid in ethanol at 50° C. to yield the title compound as light yellow foam. MS: 548.4 (MH+).
