Procedure
In analogy to Example 1, steps 4 and 5, 5-[2-(4-bromo-2-chloro-phenyl)-acetyl]-1-methyl-1H-pyridin-2-one was alkylated with iodomethane to give 5-[2-(4-bromo-2-chloro-phenyl)-propionyl]-1-methyl-1H-pyridin-2-one which was further converted to the title compound. Colorless foam. MS (m/e, ISP neg. ion)=421.8 [M−H+].
