Procedure

1.7 g (4.65 mmol) of [2-[4-(3-fluoro-benzyloxy)-3-methoxy-phenyl]-ethyl]-benzylamine, 1.74 ml (10 mmol) of di-isopropylethylamine and 0.5 ml (5.11 mmol) of 2-bromo-acetic acid methyl ester were dissolved in 20 ml of acetonitrile and the reaction was stirred at 70° C. overnight. The solvent was removed under reduced pressure, water was added to the residue and the product was extracted with ethyl acetate. The crude product was purified by flash chromatography (hexane/ethyl acetate 100:0→80:20 gradient v:v) and 1.94 g (95% yield) of the title compound were isolated as a yellow oil.
