Procedure

To a solution of 0.85 g of allyl alcohol of step C in 20 mL of anhydrous THF was added a solution of 15 mL of 0.5 N 9-BBN. The reaction was stirred for 2 days. Water (0.5 mL) was added followed with 1 mL of 30% H2O2 and 1 mL of NaOAc/water. After being stirred for 1 h, the organic phase was separated. The water solution was neutralized with HCl and extracted with EtOAc twice. The combined organic phase was dried over Na2SO4. Solvent was removed under vacuum. Column chromatography on silica gel using pure EtOAc as eluent provided 0.80 g of the title compound. MS (M+H)+ 395.
