Methyl iodide → 3-Methylthio-4-methoxyphenylacetone

Participants

Reaction Steps

A mixture of 10 g of 3-mercapto-4-methoxyphenylacetone, 9 g of anhydrous potassium carbonate, 42 g of methyl iodide, and 50 ml of methyl ethyl ketone was stirred under refluxing for 20 hours, and after cooling, the reaction mixture was filtered. The filtrate obtained was, then, evaporated to dryness. The residue formed was dissolved in ethyl acetate and after washing the solution obtained with water, ethyl acetate was distilled off and the crude crystals obtained were recrystallized from a mixture of n-hexane and ether to provide 9 g of 3-methylthio-4-methoxyphenylacetone having a melting point of 74°-75° C.
