Methyl iodide → HCID 18546484, compound

Participants

Reaction Steps

To a solution of 151 mg (0.32 mmol) N-(2′-amino-biphenyl-2-yl)-2-(3,5bis-trifluoromethyl-phenyl)-isobutyramide in 1 ml N,N-dimethylformamide under argon 130 mg (0.65 mmol) potassium hexamethyldisilazide were added at 0°. Stirring was continued for 1 h at room temperature and the reaction mixture was cooled to 0° again. At this temperature, 115 mg (0.81 mmol) methyl iodide were added. After stirring for 3 hrs at room temperature, ethyl acetate was added and the organic layer was washed with brine, dried (MgSO4) and evaporated. The residue was purified by chromatography (SiO2, ethyl acetate/CH2Cl21:1) to give 56 mg (36%) N-(2′-amino-biphenyl-2-yl)-2-(3,5-bis-trifluoromethyl-phenyl)-N-methyl-isobutyramide as colorless oil, MS(ISP): 481.1(M+H)+.
