Reaction Steps
1.0 g of E-2-amino-5-phosphino-3-pentenoic acid is suspended in 20 ml of ethanol and the suspension is saturated with hydrogen chloride gas for 2 hours at 65°. After concentration, the residue is dissolved in 10 ml of ethanol, 10 ml of propylene oxide are added and the precipitate is filtered off. Recrystallisation from water/acetone 1:1 yields E-2-amino-5-phosphino-3-pentenoic acid ethyl ester, m.p. 172°-173°.
