Chlorosuccinimide (10.29 g, 77 mmol) was added to a solution of 4-(6-fluoropyridin-2-yl)morpholine (11.7 g, 64.2 mmol) in ACN (15 mL). The reaction mixture was heated to 70° C. for 30 min. Water and DCM were added. The organic phase was separated, washed with aqueous NaHCO3, brine and subsequently dried over MgSO4. The solvent was removed under reduced pressure and the residue was purified by silica gel chromatography (5-20% EtOAc/hexanes) to afford 3.11 g of 4-(5-chloro-6-fluoropyridin-2-yl)morpholine.
