Yield:675109-26-9 71%
Reaction Conditions:
with N-Bromosuccinimide;dibenzoyl peroxide in tetrachloromethane at 85; for 2 h;
Steps:
1251.2
Step 2 Compound 1251 B (1.219g, 5.32 mmol) was dissolved in CCI4 (30 mL). NBS (947 mg, 5.32 mmol) and benzoyl peroxide (66 mg, 0.27 mmol) was added. The solution was stirred at 850C for 2 hours. After cooling down, the solid was filtered and the organic layer was washed with water (10 mL). The organic layer was dried over Na2SO4, concentrated by rotary evaporator, dried under vacuum. The residue was then dissolved in NH3-MeOH (7N, 10 mL) and transferred into a 75 mL pressure bottle. The solution was stirred at 90 0C for over night. The product was purified by C18 chromatography (CH3CN/water: 5% to 90%, with addition of 0.1% HCO2H) to give compound 1251C (800mg, 71%).
