Procedure

To a solution of 4-bromo-2-fluoro-1-nitrobenzene (1.1 g, 4.95 mmol) and tetrahydro-2H-pyran-4-amine (500 mg, 4.95 mmol) in DMF (6 mL) was added K2CO3 (1.37 g, 9.9 mmol) and the mixture stirred in sealed tube at 85° C. for 16 h. After cooling, water (100 mL) was added to the mixture and extracted with DCM (3×50 mL). The combined organic layers were washed with water (2×50 mL), brine (50 mL) and dried over anhydrous Na2SO4 then filtered and concentrated to yield the title compound which was directly used for next step without further purification.
