Sodium Bicarbonate → HCID 67171478, compound

Participants

Reaction Steps

16 mg of the compound obtained in Example 92 was dissolved in 3 mL of chloroform, and 0.1 mL of bis(2-methoxyethyl)aminosulfur trifluoride was added thereto and stirred at room temperature for 1 hour. Aqueous saturated sodium hydrogencarbonate solution was added to it and extracted with chloroform. The chloroform layer was washed with saturated saline water, dried with anhydrous sodium sulfate, and the solvent was evaporated away under reduced pressure. This was purified through column chromatography (ethyl acetate/chloroform=3/1) and then solidified from ethyl acetate/hexane solution to obtain 8 mg of the entitled compound as a yellow solid.
