Ammonium formate → N,N-dimethylmorpholine-2-carboxamide

A mixture of 4-benzyl-N,N-dimethylmorpholine-2-carboxamide (803 mg, 3.23 mmol), ammonium formate (2.15 g, 32.3 mmol) and 10% Pd/C (400 mg) in EtOH (20 mL) was heated at 50° C. for 1 hour. After cooling to room temperature, the catalyst was filtered off, washed with EtOH. The combined filtrate and washings were concentrated, and the residue was dissolved in EtOH (20 mL). Ammonium formate (2.15 g, 32.3 mmol) and 10% Pd/C (400 mg) were added to the mixture. The mixture was heated at 50° C. for 1 hour. After cooling to room temperature, the catalyst was filtered off, washed with EtOH. The combined filtrate and washings were concentrated to afford desired product (506 mg, 98.9%) as colorless oil.
