Versuchsvorschrift

A solution of methylmagnesium bromide in ether was added to a solution of 1-[5-bromo-3-(dimethylamino)-2-methoxyphenyl]-1-ethanone (4 g) in diethyl ether while stirring at −70° C. After stirring at the same temperature for 30 minutes, saturated aqueous ammonium chloride was added, extraction was performed with ethyl acetate, and the organic layer was washed with brine and then dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure to yield the title compound (3.4 g) as an oil.
