Water → 1-Benzyl 3-methyl pyrrolidine-1,3-dicarboxylate

Participants

Reaction Steps

Benzyl carbonochloridate (3.57 mL, 25.36 mmol) at 0° C. was added to methyl pyrrolidine-3-carboxylate hydrochloride (4.00 g, 24.15 mmol) and K2CO3 (6.68 g, 48.3 mmol) in THF:water (100 mL, 1:1). The reaction mixture was stirred at room temperature for 2 hours. Ether (50 mL) was added. The organic layer was separated, washed with brine and dried over sodium sulfate. After removal of the solvent, the residue was purified by chromatography (hexane:ethyl acetate, 3:1) to give 1-benzyl 3-methyl pyrrolidine-1,3-dicarboxylate (3.45 g, 54% yield) as an oil.
