실험 절차
To a solution of 2-bromophenol (8.71 g; 50.3 mmol) and bromoacetophenone (10.1 g; 50.5 mmol) in 50 ml acetone was added K2CO3 (7.02 g; 50.8 mmol). The mixture was heated to reflux for 10 h, cooled to r.t., filtered, diluted with EtOAc (100 ml), washed with HCl (1.0 M, 2×100 ml) and brine, dried over MgSO4 and concentrated. The residual solid was recrystallized from EtOAc:hexane to afford the desired material.
