Procedure
In a manner analogous to that described for α-benzyltetrahydro-β-oxo-4H-1,4-oxazinepropionic acid, benzylmalonic acid monomethyl ester was amidated with O-benzylhydroxylamine and the resulting product [MS: 314 (M+H)+ ] was saponified with 1N sodium hydroxide solution in a 9:1 mixture of methanol and water to the corresponding acid. Recrystallization of the crude product from methanol/methylene chloride/ether yielded α-[(benzyloxy)carbamoyl]hydrocinnamic acid of melting point 147°.
