To a solution of 2,4-dichloro-6-methyl-1,3,5-triazine (0.800 g, 4.87 mmol) in isopropanol (15 mL) was added DIPEA (1.3 mL) and 3-(4-chloro-2-fluorophenoxy)azetidine (0.600 g, 2.92 mmol) and the reaction mixture was stirred at RT for 1 h. The mixture was concentrated under reduced pressure and extracted with EtOAc (2×40 mL). The organic extracts were washed with brine, dried over anhydrous sodium sulfate and concentrated under reduced pressure to obtain 2-chloro-4-(3-(4-chloro-2-fluorophenoxy)azetidin-1-yl)-6-methyl-1,3,5-triazine (1.0 g) as a solid. Observed mass (M+1): 329. The crude material was taken to next step without further purification.
