Reaction Steps

A solution of dimethyl itaconate (4.08 g, 25.8 mmol) in MeOH (3.2 mL) was added to a solution of 2,4-dimethoxybenzylamine (4.32 g, 25.8 mmol) in MeOH (9.6 mL) via cannula at room temperature. After 18 h at room temperature the reaction was concentrated in vacuo to afford crude 1-(2,4-dimethoxybenzyl)-5-oxo-pyrrolidine-3-carboxylic acid methyl ester as a viscous oil.
