Versuchsvorschrift
5-((dimethylamino)methyl)-N-(4-methoxybenzyl)pyridin-3-amine (LVI) (0.15 g, 0.56 mmol) was dissolved in TFA (2.0 mL) and stirred at room temperature for 1 h. The TFA was removed, and the residue was treated with 7N ammonia in MeOH/chloroform mixture (7/93) to neutralize the TFA and concentrated again to a residue. The residue was purified by flash silica gel chromatography utilizing a 4 g Thomson normal-phase silica gel cartridge (100% CHCl3→3:97 MeOH[7N NH3]:CHCl3) to afford 5-((dimethylamino)methyl)pyridin-3-amine (LVII) (0.044 g, 0.29 mmol, 52% yield) as a brown oil. ESIMS found for C8H13N3 m/z 152 (M+H).
