実験手順
To a solution of 4-(2-bromo-5-fluorophenoxy)piperidine (3.281 g, 11.97 mmol) in EtOH (28.5 mL) was added ethyl 2-chlorooxazole-4-carboxylate (1 g, 5.70 mmol) and DIPEA (1.990 mL, 11.39 mmol). The reaction mixture was stirred at rt for 5 h. The solvent was evaporated under reduced pressure. The residue was diluted with 1N HCl and extracted with EtOAc. The combined organic layers were dried (MgSO4), filtered and evaporated under reduced pressure to give the title compound.
