Acetone → HCID 10634057, compound

Participants

Reaction Steps

A mixture of 6.23 g (25 mmol) of 9c and 5.71 g (50 mmol) of potassium thiolacetate in 100 mL of acetone was heated at reflux for 30 minutes. After cooling to room temperature, the crude reaction mixture was filtered, and the filtrate was concentrated, in vacuo. The residue obtained was partitioned between ether and water (150 mL each). The layers were separated and the aqueous phase was extracted with 100 mL of ether and 100 mL of ethyl acetate. The combined organic extracts were dried over Na2SO4 and concentrated, in vacuo, yielding a red oil which was purified by flash chromatography. Elution with hexane/ethyl acetate (9:1) yielded the product as a yellow solid (5.61 g, 92% yield) mp 67°-68° C.
