To 0.040 g (0.13 mmol) (S)-1-{4-[3-(4-ethoxy-phenoxy)-azetidin-1-yl]-phenyl}-ethylamine (X.1) in 1.5 mL THF are added 54 μL (0.38 mmol) TEA and 0.021 g (0.13 mmol) 4-bromo-2(5H)-furanone. The mixture is stirred for 12 h at 80° C. After concentration in vacuo the residue is purified by HPLC (SunfireC18, MeOH/water (+0.3% formic acid)) to yield the desired product.
