Procedure
2.0 g of E-2-amino-5-phosphono-3-pentenoic acid are suspended in 30 ml of n-octanol and the suspension is saturated with hydrogen chloride gas for 4 hours at 70°. The mixture is concentrated in vacuo at 70° to half its volume, 50 ml of diethyl ether and 15 ml of propylene oxide are added and the whole is filtered. Recrystallisation from water/acetone 1:1 yields E-2-amino-5-phosphono-3-pentenoic acid octylester, m.p. 161°-162°.
