Versuchsvorschrift

0.303 g (0.94 mmol) of tert-butyl 2-(4-{[(2-methoxyethyl)amino]methyl}phenoxy)-2-methylpropanoate (Example III-33) is initially charged in 5 ml of dimethylformamide. At room temperature, 0.319 g (1.03 mmol) of 2-bromo-N-(4-cyclohexyl-2-methylphenyl)acetamide (Example III-19) and 0.086 g (1.03 mmol) of sodium bicarbonate are added. The mixture is stirred at 90° C. for 2 hours. The reaction mixture is then allowed to cool, and water is added. The mixture is extracted with ethyl acetate and the organic phase is washed with water and saturated sodium chloride solution. The organic phase is dried over sodium sulphate and freed from the solvent under reduced pressure. The residue is purified chromatographically on silica gel (cyclohexane/ethyl acetate 3:1) and the product is dried under reduced pressure. This gives 0.464 g (90% of theory) of the title compound.
