A solution of 925 mg (4.05 mmol) 2′-methyl-4-nitro-biphenyl-2-ylamine and 1.03 ml (6.08 mmol) N-ethyldiisopropylamine in 9 ml CH2Cl2 was cooled in an ice bath and a solution of 1.42 g (4.46 mmol) 2-(3,5-bis-trifluoromethyl-phenyl)-2-methyl-propionyl chloride in 1 ml CH2Cl2 was added dropwise. The reaction mixture was kept at room temperature for 2 hrs. After addition of CH2Cl2, the organic layer washed with 1 N NaOH solution and 1 N HCl solution, dried (MgSO4) and evaporated to give 1.84 g (89%) 2-(3,5-bis-trifluoromethyl-phenyl)-N-(2′-methyl-4-nitro-biphenyl-2-yl)-isobutyramide as yellow crystals, MS (ISP): 511.3 (M+H)+.
