Versuchsvorschrift
A 100 mL round-bottom flask was charged with tert-butyl 4-[[3-fluoro-2-(morpholin-4-yl)phenyl]methyl]piperazine-1-carboxylate (1.00 g, 2.64 mmol, 1.00 equiv), dichloromethane (20 mL). The mixture was cooled to 0° C. Trifluoroacetic acid (2 mL) was added dropwise at 0° C. The resulting solution was stirred overnight at room temperature and concentrated under reduced pressure to yield 0.600 g (crude) of 4-[2-fluoro-6-(piperazin-1-ylmethyl)phenyl]morpholine as light yellow oil. LCMS (ESI, m/z): 280 [M+H]+.
