Procedure

Compound 92 (1.58 g, 5.37 mmol) and morpholine (0.64 mL, 10.7 mmol) were dissolved in 1,2-dichloroethane (26 mL), and sodium triacetoxyborohydride (3.41 g, 16.1 mmol) was 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 93 (1.15 g, 57%).
