Acetone → HCID 11140821, compound

Participants

Reaction Steps

A mixture of 1.00 gm (0.0043 mole) of 3-hydroxyphenoxathiin 10,10-dioxide (Example 7) 1.48 gm (0.0107 mole) of anhydrous granular potassium carbonate, 5.5 mL of 2-iodopropane (Aldrich Chemical Co.), and 60 mL of acetone were stirred overnight. The acetone was removed under water pump vacuum and the residue mixed with methylene chloride and filtered. The filtrate was washed with 2×200 mL of water and dried over magnesium sulfate. The solvent was removed under water pump vacuum to give an oil. Some hexane was added to the oil and the mixture heated on a steam bath. This gave a white solid which was recrystallized from ethyl acetate/hexane to yield 0.75 gm of 3-isopropoxyphenoxathiin 10,10-dioxide, m.p. 94-95°.
