Participants

Reaction Steps

2.0 g of E-2-amino-5-phosphono-3-pentenoic acid are suspended in 40 ml of n-butanol and the suspension is saturated with hydrogen chloride gas for 3 hours at 40°. After concentration, the residue is dissolved in 30 ml of n-butanol, 15 ml of propylene oxide are added and the precipitate is filtered off. Recrystallisation from water/acetone 1:1 yields E-2-amino-5-phosphono-3-pentenoic acid butyl ester, m.p. 160°-161°.
