Procedure
4-Bromo-2-fluorophenol (1.0 g, 5.24 mmol), 2-chloro-N,N-diethylethanamine HCL (0.90 mg, 5.24 mmol) and Cs2CO3 (8 g, 25 mmol) were combined in DMF (20 mL) and the mixture was heated at reflux over night. H2O was added and the mixture was extracted with EtOAc, then washed with 2N NaOH and brine. The organic layers were combined, dried over Na2SO4 and concentrated to a brown oil. Flash chromatography (gradient eluent: 10-50% EtOAc in hexanes) of the crude concentrate afforded title compound 56.
