---|---|---|
With potassium carbonate; In N,N-dimethyl-formamide; at 20℃; | General procedure: Compound 5 was dissolved in anhydrous DMF (10mL) in the presence of anhydrous K2CO3 (2eq), followed by the addition of appropriate substituted phenol (1.1eq) or substituted phenylamine (1.1eq). The reaction mixture was stirred at room temperature overnight. The solvent was removed under reduced pressure, and water (20mL) was added. Extracted with ethyl acetate (2×10mL), and the organic phase was washed with saturated sodium chloride (10mL), and dried over anhydrous Na2SO4 to give the corresponding crude product, which was purified by flash column chromatography (EtOAc : petroleum ether=1:1) to afford compounds 6[21]. |
