Procedure

In analogy to example 203, step 1, 5-[(E)-3-(4-chloro-2-methyl-phenyl)-acryloyl]-1-methyl-1H-pyridin-2-one (example 323, step 3) was reacted with 4-hydroxyphenylboronic acid in the presence of chloro(1,5-cyclooctadiene)rhodium(I) dimer and sodium hydrogencarbonate in 1,4-dioxane and water at 60° C. to give the title compound as a colourless solid, MS (ESI−): m/z=380.1 [M−H]−.
