実験手順

A 250 mL round-bottom flask containing a magnetic stirring bar equipped with a reflux condenser was charged with 1.6 g (0.00717 mol) of compound 62, 0.8 mL (0.00717 mol) of thioglycolic acid and 50 mL of 1,2-dichloroethane. At 0° C., 1.4 mL (0.0107 mol) of BF3.Et2O dissolved in 10 mL of 1,2-dichloroethane was added slowly. The resulting mixture was stirred for 15 minutes and then 100 mL of water and 10 mL of HCl (IN) were added. The product was extracted with 2×50 mL of ethyl acetate. The organic layer was dried over magnesium sulfate, filtered and evaporated to dryness. The crude product was used for the next step (preparation of Example 148).
