A 100 mL round-bottom flask was charged with tert-butyl 4-[[4-(morpholin-4-yl)-2-(trifluoromethyl)phenyl]methyl]piperazine-1-carboxylate (1.60 g, 3.73 mmol, 1.00 equiv), dichloromethane (10 mL). Trifluoroacetic acid (3.10 g, 27.2 mmol, 7.30 equiv) was added at 0° C. The resulting solution was stirred overnight at room temperature and concentrated under reduced pressure to yield 1.00 g (81% yield) of 4-[4-(piperazin-1-ylmethyl)-3-(trifluoromethyl)phenyl]morpholine as yellow oil. LCMS (ESI, m/z): 330 [M+H]+.
