Yield: 91.5%

Reaction Conditions:

with boron tribromide in dichloromethane at -30; for 2 h;

Steps:

1-(2,3-dihydroxyphenyl)ethan-1-one, 30
BBr3 (600 μL, 6.2 mmol) was added to a DCM solution of 29 (383 mg, 3.1 mmol) at -30 . After stirring for 2 h, the reaction was quenched by dropwise added saturated NaHCO3 agueous solution (20 mL) and extracted with DCM. The organic layer was dried over Na2SO4, filtered and concentrated in vacuo to give 30 as light white solid (302 mg, 91.5%).
