Reaction Steps

To a solution of 3-(2,4-dichlorophenoxy)azetidine (1.0 g, 4.6 mmol) in isopropanol (14 mL) was added N,N-diisopropylethylamine (DIPEA) (1.0 mL, 6.9 mmol) and 2,4-dichloropyrimidine (0.686 g, 4.6 mmol and the reaction mixture was heated at 80° C. for 7 h. The mixture was concentrated under reduced pressure and extracted with EtOAc (2×20 mL) and water (2×20 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-(2,4-dichlorophenoxy)azetidin-1-yl)pyrimidine (0.600 g, 40%) as a solid. Observed mass (M+1): 330.0
