Procedure

In analogy to example 161, step 1, 5-(3-(4-chloro-2-methylphenyl)-3-(4-(methylsulfonyl)phenyl)propanoyl)pyridin-2(1H)-one (example 339, step 2) was reacted with methyl 3-bromopropanoate in the presence of potassium carbonate and a catalytic amount of tetrabutylammonium iodide to give the title compound as a light yellow solid, MS (ESI+): m/z=518.4 [M+H]+.
