PROCEDURE

实验过程

Compound 42 (249 mg, 0.725 mmol), 2-phenyl-7-methoxy-4-quinolinol (310 mg, 1.23 mmol) and PPh3 (580 mg, 2.21 mmol) were dissolved in dry THF and the temperature was lowered to 0° C. DIAD (435 uL. 2.21 mmol) dissolved in 2 mL dry THF, was added to the mixture during five minutes. After two hours the temperature was raised to room temperature and the solution was stirred overnight. Evaporation and purification by flash column chromatography (toluene/EtOAc gradient 6:1 to 4:1) gave 43 (324 mg, 78%).
