반응 단계
Trifluoro-methanesulfonic anhydride (14.35 mL, 77.3 mmol) was added to a CH2Cl2 (150 mL) solution of 6-hydroxy-3,4-dihydro-2H-naphthalen-1-one (11.40 g, 70.3 mmol), N-methylmorpholine (8.5 mL, 77.3 mmol) and DMAP (130 mg, 1 mmol) in 5 min at −80° C. The mixture was warmed to 0° C. in 1 h then poured into a cold solution of saturated NH4Cl. The mixture was diluted with CH2Cl2 (400 mL), washed with H2O, dried over MgSO4, filtered, and concentrated in vacuo to provide the crude compound which was purified by column chromatography (silica, 0 to 60% CH2Cl2 in hexane) to provide the title compound.
