Reaction Conditions

Reaction Steps

Thionyl chloride (5 mL) was added to a cold (0° C.) stirred solution of pyrrolidine-3-carboxylicacid (500 mg, 4.34 mmol) in EtOH (25 mL) and continued stirring at 80° C. for 12-16 h. The reaction mixture was concentrated under reduced pressure to afford 600 mg (crude) of ethyl pyrrolidine-3-carboxylate, which was used as such in the next step without purification.
