Reaction Steps
To a solution of 0.63 g (1.50 mmol) biphenyl-2-carboxylic acid 3,5-bis-trifluoromethyl-benzylamide in 10 ml N,N-dimethylformamide 0.08 g (1.98 mmol) sodiumhydride (60% dispersion in mineral oil) was added and the reaction mixture was stirred for 1 hr. After the addition of 0.15 ml (2.4 mmol) methyl iodide at 0°, the reaction mixture was stirred for 3 hrs. at RT. The reaction mixture was distributed between 50 ml H2O, 50 ml brine and 50 ml CH2Cl2. The phases were separated, the aqueous layer washed twice with 50 ml CH2Cl2. The combined organic layers were dried (MgSO4), filtered and evaporated. The residue was purified by chromatography (SiO2, ethyl acetate/CH2Cl2 15:1) to give 0.50 g (76%) biphenyl-2-carboxylic acid (3,5-bis-trifluoromethyl-benzyl)-methyl-amide as colorless solid, m.p. 97-88°.
