Reaction Conditions

Reaction Steps

At 0° C., trifluoroacetic acid (8 ml) was added to a solution of N-[(1R)-1-benzyl-2-((2S)-2-((dimethylamino)methyl)pyrrolidin-1-yl)-2-oxoethyl]-N-methylcarbamic acid tert-butyl ester (2.26 g, 5.80 mmol) in dichloromethane (8 ml). The reaction mixture was stirred for 20 min at 0° C. The solvent was removed in vacuo. Dichloromethane (70 ml) was added, and the solvent was removed in vacuo. The latter procedure was repeated two times. The crude product was purified by flash chromatography on silica (90 g), using dichloromethane/methanol/25% aqueous ammonia (100:10:1) as eluent, to give 1.24 g of (2R)-1-((2S)-2-((dimethylamino)methyl)pyrrolidin-1-yl)-2-methylamino-3-phenylpropan-1-one.
