Procedure

Compound 43 (4.71 g, 9.50 mmol) was dissolved in dichloromethane (100 mL), and dimethyl sulfide (29.4 mL, 400 mmol) and boron trifluoride-diethyl ether complex (24.6 mL, 200 mmol) were added thereto, followed by stirring overnight at room temperature. The reaction mixture was poured into 28% aqueous ammonia, 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 to afford the entitled Compound 44 (1.36 g, 38%).
