Procedure

Compound 85 (250 mg, 0.836 mmol) was dissolved in 1,2-dichloroethane (4 mL), and morpholine (0.15 mL, 1.67 mmol) and sodium triacetoxyborohydride (531 mg, 2.51 mmol) were added thereto, followed by stirring overnight at room temperature. Water was added to the reaction mixture, followed by extraction with chloroform. The organic layer was washed with a saturated aqueous solution of sodium chloride and dried over anhydrous magnesium sulfate, and then the solvent was distilled away under reduced pressure. The resulting residue was purified through silica gel column chromatography (chloroform:methanol=30:1) to afford the entitled Compound 86 (302 mg, 98%).
