Procedure

To a solution of EXAMPLE 155A (1.7 g) in tetrahydrofuran (20 mL) was added a 0.5 M 9-borabicyclo[3.3.1]nonane-tetrahydrofuran solution (50 mL, 0.5 M) at 0° C. After the reaction mixture was stirred for 24 hours at room temperature, a 0.5 M NaOH aqueous solution (30 mL) and 30% H2O2 aqueous solution (5.5 mL) were added. After the reaction mixture was stirred for 16 hours, the reaction was then quenched by adding water (15 mL). The reaction mixture was extracted with ethyl acetate, and the organic layer was washed with water and a saturated aqueous NaCl solution. After the organic layer was dried over Na2SO4, and filtered, the solvent was evaporated under reduced pressure. The crude product was purified on a silica gel column, eluting with 10-50% ethyl acetate in hexanes, to provide the title compound.
