How is S-Methyl ethanethioate (CAS: 1534-08-3) typically synthesized?

S-Methyl ethanethioate can be synthesized by the reaction of ethanethiol with methyl iodide in the presence of a base such as potassium carbonate. The reaction is typically conducted in a solvent like acetonitrile at room temperature. High yields are achieved with good selectivity towards the desired product. This method is widely used due to its simplicity and good control over the reaction conditions.
