실험 절차
A solution of 4-(2-Chloro-ethyl)-benzoic acid (20 g, 108 mmol) in DMF (200 mL) is treated with K2CO3 (59.7 g, 432 mmol) and Mel (16.8 mL, 270 mmol) and stirred at 23 C for 18 h. The reaction mixture is diluted with EtOAc (450 mL) and washed with H2O (2×150 mL), saturated aqueous NaHCO3 (1×200 mL), brine (1×200 mL), dried (MgSO4), and concentrated to afford the title compound as a yellow oil.
