実験手順

A solution of 1-bromo-3-chloro-5-fluorobenzene (5.05 g, 24.11 mmol), morpholine (3.15 mL, 36.2 mmol), potassium carbonate (6.66 g, 48.2 mmol), and DMF (45 mL) was stirred at 60° C. for 48 h, then at 110° C. for 24 h. The reaction mixture was concd, and the resulting residue was partitioned between EtOAc and water. The organic phase was dried over magnesium sulfate and concd, affording a crude material that was purified by column chromatography (silica; 0-10% EtOAc in hexanes) to yield 4-(3-bromo-5-chlorophenyl)morpholine as a white amorphous solid. Mass Spectrum (ESI) m/e=276.0 (M+1).
