benzyl (2R)-2-carbamoylpyrrolidine-1-carboxylate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of the amide from Example 33 (1.56 g, 6.28 mmol) in 10 mL of dimethylformamide dimethyl acetal was heated to 120° C. for 2 h. After cooling, the solvent was evaporated under high vacuum and the residue was taken to the next step without further purification. After cooling the solvent was evaporated under high vacuum the residue was taken to the next step without further purification
