Participants

Reaction Steps

To tert-butyl 4-{2-[(dimethylamino)methyl]phenyl}-piperazine carboxylate (Step 2) (0.68 g, 2.1 mmol) dissolved in CH2Cl2 (12 mL) was added TFA (6 mL). After stirring the reaction at RT for 1 h, the solvent was concentrated in vacuo and the residue was partitioned between CH2Cl2 and satd NaHCO3. The organic layer was washed with brine and the combined aqueous layer were extracted with a mixture of CH2Cl2 and 30% MeOH. The combined organic layer was dried over Na2SO4, filtered and concentrated in vacuo to give dimethyl[(2-piperazinylphenyl)methyl]amine as a yellow oil (0.35 g). MS m/z: 220 (M+H). Calc'd for C13H21N3: 219.33.
