Versuchsvorschrift
To a solution of 3-(4-chloro-2-fluorophenoxy) azetidine (3.6 g, 18.0 mmol) in acetonitrile (60 mL, 3 mL/mmol) was added TEA (7.2 mL, 50.0 mmol) and 2, 4-dichloro-1, 3, 5-triazine (3.0 g, 20.0 mmol) and the reaction mixture was stirred at RT for 1 h. The reaction mixture was concentrated under reduced pressure and extracted with EtOAc (2×50 mL). The organic extracts were washed with brine, dried over anhydrous sodium sulfate and concentrated under reduced pressure. Purification by silica gel column chromatography provided 2-chloro-4-(3-(4-chloro-2-fluorophenoxy)azetidin-1-yl)-1,3,5-triazine (0.800 g, 20%) as a solid. Observed mass (M+1): 315.0
