Versuchsvorschrift

Step 3): A solution of 4-(N-methylamino)methyl-1-diphenylmethylpiperidine (1.8 g, 6.0 mmol), isatoic anhydride (0.9 g, 5.5 mmol) and 4-dimethylaminopyridine (0.74 g) in DMF (25 ml) was stirred at room temperature for 2 hours. The reaction mixture was poured into 1% NaHCO3 solution and extracted with ethyl acetate. The organic layer was washed with water, dried and concentrated. The residue was purified by column chromatography on silica gel (ethyl acetate and hexane) to give 2-amino-N-methyl-N-[(1-diphenylmethylpiperidin-4-yl)methyl]benzamide (1.5 g, 67%).
