Reaction Steps

A solution of 53 mg (0.25 mmol) (2′-methoxy-biphenyl-2-yl)-methyl-amine and 0.064 ml (0.375 mmol) N-ethyldiisopropylamine in 4 ml CH2Cl2 was cooled in an ice bath and a solution of 88 mg (0.275 mmol) 2-(3,5-bis-trifluoromethyl-phenyl)-2-methyl-propionyl chloride in 1 ml CH2Cl2 was added dropwise. The reaction mixture was stirred overnight at room temperature. Ethyl acetate was added and the organic layer was washed with saturated Na2CO3 solution, 1 N HCl solution, dried (MgSO4) and evaporated. The residue was purified by chromatography (SiO2, hexane/ethyl acetate 4:1) to give 107 mg (87%) 2-(3,5-bis-trifluoromethyl-phenyl)-N-(2′-methoxy-biphenyl-2-yl)-N-methyl-isobutyramide as orange crystals, MS (ISP): 496.1 (M+H)+.
