実験手順

A solution of 2-phosphonopropionic acid (11.2 g., 0.073 moles) in methanol (150 ml.) is heated at reflux for eighteen hours. The methanol is removed in vacuo. Electrophoresis (0.1 N NH4HCO3, 2000 V, 20 minutes, 7.5 cm) indicates complete conversion to the desired product, methyl 2-phosphonopropionate; yield quantitative.
