Reaction Steps

Part A. Lawesson's reagent (90 mg, 0.22 mmol) was added to a stirred slurry of benzyl (S)-2-carbamoyl-pyrrolidine-1-carboxylate (100 mg, 0.40 mmol) in toluene (3 mL) at ambient temperature. The reaction mixture was heated to 100° C. for 3 h then the solvents were removed. The residue was purified by flash silica gel chromatography yielding benzyl (S)-2-thiocarbamoylpyrrolidine-1-carboxylate as white solid (108 mg, crude quantative yield): HPLC (method 1) tR=2.55 min, Purity 100%; LCMS (method 4) tR=1.34 min, m/z 287 (M+H).
