Procedure

Into 100 ml. of absolute ethanol was placed 28 g. (0.2 mole) of phosphonoacetic acid. The solution was treated with a stream of dry hydrogen chloride at 0° C. for 45 minutes. After refluxing for 3 hours the solution was allowed to stand overnight at room temperature. Evaporation of the solvent yielded a viscous oil, which was dried in vacuo over P2O5 and NaOH.
