Procedure

15.26 g (59.3 mmol) of crude 2-(3-methoxy-4-benzyloxyphenyl)ethylamine, 9.09 g (89.0 mmol) of triethylamine and 100 ml of tetrahydrofuran were mixed and cooled to about 0° C. and then 5.44 g (32.28 mmol) of (4-methylphenyl)acetyl chloride was added dropwise thereto. The mixture was stirred at 0° C. for 30 minutes and further at room temperature for 3 hours. Water was added to the reaction mixture, which was followed by extracted with ethyl acetate, washed with 5% hydrochloric acid and saturated brine subsequently, dried over anhydrous magnesium sulfate and the solvent was distilled off under reduced pressure. The residue was washed with hexane and dried to give 19.48 g of N-[2-(4-benzyloxy-3-methoxyphenyl)ethyl]-2-(4-methylphenyl)acetamide.
