Reaction Conditions:
with methanol;potassium carbonate in tetrahydrofuran at 70; for 24 h;Inert atmosphere;Concentration;
Steps:
1.7 7) Synthesis of compounds of formula (7)
Type (6) compound (200 mg, 0 . 46mmol) dissolved in methanol (10 ml) and tetrahydrofuran (2 ml) in the mixed solvent, adding anhydrous potassium carbonate (630 mg, 4 . 6mmol), nitrogen protection, heating to 70 °C, reaction 24 hours. TLC detection after the reaction is complete, the solvent is removed under reduced pressure, the addition of water (10 ml), diluted hydrochloric acid to adjust the pH of less than 7, dichloromethane is used for extraction (10 ml × 3), the combined organic phase, saturated salt water (20 ml × 3) washing, water-freeNa2SO4drying, concentration, silica gel column chromatography (DCM:MeOH=40:1) purification, to obtain white solid (7) compound (160 mg), yield 92%.
