Methyl pyruvate synthesis

14synthesis methods
Methyl pyruvate has been prepared from the silver salt of pyruvic acid and methyl iodide;  from the free acid, by the ethanol-vapor method without a catalyst, by azeotropic removal of the water produced by the reaction of methanol in the presence of p-toluenesulfonic acid (the present method), and by refluxing with methanol in ethylene dichloride using ethanesulfonic acid as a catalyst (73% yield). Pyruvic esters have also been prepared by the catalytic dehydrogenation of lactic acid esters and by the oxidation of ethyl lactate with potassium permanganate.
