Versuchsvorschrift
A 100 mL round-bottom flask was charged with tert-butyl 4-[[2-methyl-4-(3-methylphenyl)phenyl]methyl]piperazine-1-carboxylate (2.00 g, 5.26 mmol, 1.00 equiv), trifluoroacetic acid (8 mL), dichloromethane (40 mL). The resulting solution was stirred for 1 h at room temperature and concentrated under reduced pressure to yield 1.50 g (crude) of 1-[[2-methyl-4-(3-methylphenyl)phenyl]methyl]piperazine as light yellow oil. LCMS (ESI, m/z): 281 [M+H]+.
