A mixture of 2,6-dichloro-4-(1-(oxetan-3-yl)piperidin-4-yl)pyridine (450 mg, 1.57 mmol), 3-methoxyazetidine hydrochloride (963 mg, 7.83 mmol) and DIPEA (3 mL, 16.9 mmol) in DMSO (5 mL) was stirred at 100° C. for 16 h. The mixture was poured into water and extracted with EtOAc. The organic layer was washed with brine, dried over Na2SO4, evaporated and purified by flash column chromatography on silica gel (30% ethyl acetate in petroleum ether) to give 2-chloro-6-(3-methoxyazetidin-1-yl)-4-(1-(oxetan-3-yl)piperidin-4-yl)pyridine (320 mg, 60.3% yield). LCMS (ESI) [MH]+=337.8
