Participants

Reaction Steps

to -60° C. To this mixture was added a solution of 33.7 mg (0.0944 mmol) of the compound prepared in Example 5 in 1.4 ml of anisole and 0.2 ml of dichloromethane, and the mixture was stirred for 30 minutes at the same temperature. And then, to the mixture was added a solution of 143 mg (1.7 mmol) of sodium bicarbonate in 4 ml of 0.1 M phosphate buffer (pH 7.0), and the mixture was stirred for 30 minutes under ice-cooling. After the reaction mixture was filtered, the filtration was washed twice with dichloromethane. The aqueous layer was separated, and purified by reverse phase silica gel column chromatography (elution with 10% methanol-water) to give 5.74 mg (yield: 23.5% of the title compound.
