Participants

Reaction Steps

To a solution of 3.09 g (5.15 mmol) 2-(3,5-bis-trifluoromethyl-phenyl)-N-[4-iodo-6-(4-methyl-piperazin-1-yl)-pyridin-3-yl]-isobutyramide in 30 ml N,N-dimethylformamide were added at 0° C. 6.8 ml (6.2 mmol) of a 0.91 M solution of potassium bis(trimethylsilyl)amide in tetrahydrofuran. After stirring at 0° C. for 40 min 0.352 ml (5.66 mmol) iodomethane were added. The mixture was stirred for 2 days in a closed flask. The reaction mixture was concentrated in vacuo and purified by flash chromatography to give 980 mg (31%) of the title compound as a brown oil.
