Versuchsvorschrift

To a solution of N-(2-methoxyethyl)-2-methyl-4′-(trifluoromethyl)-1,1′-biphenyl-3-amine (500 mg, 1.62 mmol) in acetonitrile (30 mL) was added ethyl [4-(bromomethyl)-2-methylphenoxy]acetate (488 mg, 1.7 mmol) and N,N-diisopropylethylamine (295 μl, 1.7 mmol). The resultant mixture was heated for 4.5 h at 80° C. On cooling the solvents were removed in vacuo, the residue diluted with water and extracted with CH2Cl2. The organic solution was passed through a hydrophobic frit and the solvent removed in vacuo. Purification by Biotage™ chromatography (silica, 40 g) eluted with 5% EtOAc/cyclohexane afforded the title compound as a colourless oil (503 mg).
