Versuchsvorschrift

1.0 g (4.3 mmol) (S)—N-{1-[4-(3-Hydroxy-azetidin-1-yl)-phenyl]-ethyl}-acetamide (V.1), 0.6 g (5.2 mmol) 2,4-difluoropyridine and 2.0 g (6.2 mmol) cesium carbonate are combined in 40 mL DMF and the mixture is stirred for 12 h at 80° C. Water is added and the mixture is extracted twice with ethylacetate. After concentration in vacuo the residue is purified by chromatography (silica; ethylacetate) to yield the desired product.
