Reaktionsschritte

A mixture of N-benzyl-2-chloroacetamide (17.8 g), DIPEA (19.5 mL) and 4-fluoro-2-methyl-aniline (10.6 mL) in anhydrous DMF (174 mL) was stirred at 100° C. for 40 hours under a Nitrogen atmosphere. After cooling to r.t., the dark solution was partitioned between AcOEt (200 mL) and water (200 mL). The separated aqueous phase was extracted with further AcOEt (3×200 mL). The combined organic extracts were washed with water (200 mL), dried and concentrated in vacuo. The residue was purified by flash chromatography (CH/AcOEt 2:8) to give a dark solid, which was triturated with CH to give the title compound as a beige solid (16.2 g).
