81% | With Jones reagent In acetone at 0℃; for 1 h; | The total amount (42.71 g, 79 mmol) of Compound 1d obtained was suspended in acetone (350 mL)Next, Jones reagent (2.67 mol / L, 71.0 mL, 190 mmol) was added thereto at 0 °C. The mixture was stirred at 0 ° C. for 1 hour. After diluting the reaction mixture with dichloromethane and water,Sodium bisulfite was added at 0 ° C.The resulting solution was then separated, washed with water and saturated salt solution and dried over magnesium sulfate. After filtering off the magnesium sulfate, the liquid was concentrated under reduced pressure. Next, the precipitated solid was collected by filtration and washed with diisopropyl ether to obtain Compound 1e (26.94 g, 81percent) |
