실험 절차
The title compound of step 6 (140 mg, 1.04 mmol) was dissolved in ACN (5 mL) and NBS (188 mg, 1.06 mmol) was added. After stirring at rt for 1.5 h, purification by silica gel chromatography (PE/EtOAc=1:1) gave the title compound (196 mg, 89.5%) as a white solid. 1H NMR (CD3Cl, 300 MHz): δ 7.33 (s, 1H), 3.53 (s, 3H), 2.85-2.97 (m, 4H), 2.05-2.13 (m, 2H). LCMS: 228, 230 (M+1)+
