[C:1]([NH:4][CH2:5][CH:6]1[O:11][CH2:10][CH2:9][N:8](CC2C=CC=CC=2)[CH2:7]1)(=[O:3])[CH3:2]>C(O)C.C(O)(=O)C.[C].[Pd]>[C:1]([NH:4][CH2:5][CH:6]1[O:11][CH2:10][CH2:9][NH:8][CH2:7]1)(=[O:3])[CH3:2]In a solution of 2-(N-acetylaminomethyl)-4-benzylmorpholine (20 g, 80.7 mmol) in ethanol-acetic acid (20/1, 210 ml) was suspended 2.0 g of 10% palladium-carbon and the mixture was stirred at 60° C. under hydrogen stream for 22 hours. The reaction mixture was filtered with Celite, the solvent was distilled off from the filtrate under reduced pressure to give crude 2-(N-acetylaminomethyl)morpholine (15.62 g). Yield=100%. This compound was used for the subsequent reaction without purification.
