Reaction Steps

In analogy to the procedure described in example 50k), 2,6-dimethyl-N-piperidin-4-yl-terephthalamic acid (example 126b) 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 solid. MS: 520.3 (MH+).
