Benzylamine → Methyl 1-benzyl-5-oxopyrrolidine-3-carboxylate

Participants

Reaction Steps

A solution of dimethyl itaconate (50 g, 0.32 mole) in methanol (40 ml) was treated with benzylamine (34.6 ml, 0.32 mole) and the mixture heated under reflux for 2.5 h. The solution was then concentrated in vacuo and the residue purified by distillation (b.p. 162° C.-170° C./0.2 mmHg) to give a pale yellow oil. This solidified on standing to give the title compound (D16) as a beige solid (66.2 g, 89%), m.p. 62° C.-63° C.
