Yield:71556-74-6 81.4%
Reaction Conditions:
with boron tribromide in dichloromethane at 0; for 3.5 h;
Steps:
3 Embodiment 3: preparation of compoundIII:
The 0.5g compound II dissolved in 15 ml anhydrous DCM (dichloromethane), will 1.44g boron tribromide soluble in 4mLDCM (dichloromethane) is applied to the above-mentioned reaction solution. Cooling to 0 °C reaction 3.5h rear, using saturated NaHCO3solution to adjust pH to 5-6, separating, the aqueous phase used 10mLDCM extraction, combined with the phase, using anhydrous NaSO4drying, was eventually 0.385g white solid (yield 81.4%).
