Versuchsvorschrift
A 100 mL round-bottom flask was charged with tert-butyl 4-[[6-methyl-5-(2-methylphenyl)pyridin-2-yl]methyl]piperazine-1-carboxylate (1.00 g, 2.62 mmol, 1.00 equiv), dichloromethane (20 mL). Trifluoroacetic acid (2.5 mL) was added dropwise at 0° C. The resulting solution was stirred overnight at room temperature and concentrated under reduced pressure to yield 0.800 g (crude) of 1-[[6-methyl-5-(2-methylphenyl)pyridin-2-yl]methyl]piperazine as a yellow solid. LCMS (ESI, m/z): 282 [M+H]+.
