Reaction Steps

At 0° C., trifluoroacetic acid (20 ml) was added to a solution of N-[(1R)-1-benzyl-2-(4-((dimethylamino)methyl)piperidin-1-yl)-2-oxoethyl]-N-methylcarbamic acid tert-butyl ester (1.22 g, 3.02 mmol) in dichloromethane (20 ml). The reaction mixture was stirred for 1 h at 0° C. The solvents were removed in vacuo. The residue was dissolved in dichloromethane (70 ml) and the solvent was removed in vacuo. The latter procedure was repeated two times. The crude product was purified by flash chromatography on silica (100 g), using dichloromethane/methanol/25% aqueous ammonia (100:10:1), to give 659 mg of (2R)-1-(4-((dimethylamino)methyl)piperidin-1-yl)-2-(methylamino)-3-phenylpropan-1-one.
