실험 절차
The mixture of bromide 184 (2.52 g, 6.85 mmol) in N,N-diethylaniline (8 mL) was stirred at 200° C. for 45 hours. The mixture was cooled to rt and extracted with EtOAc/aq. 1N HCl solution (100 mL/100 mL). The organic layer was washed with brine, dried over MgSO4, filtered, and concentrated in vacuo. The residue was purified by silica gel column chromatography to provide the desired product 185 (2.3 g, 91%).
