Reaction Steps

A 100 mL round-bottom flask was charged with tert-butyl 4-[[5-chloro-2-(morpholin-4-yl)phenyl]methyl]piperazine-1-carboxylate (2.90 g, 7.32 mmol, 1.00 equiv), dichloromethane (35 mL). The mixture was cooled to 0° C. and trifluoroacetic acid (7 mL) was added dropwise. The resulting solution was stirred overnight at room temperature. The resulting solution was concentrated under reduced pressure to yield 2.60 g (crude) of 4-[4-chloro-2-(piperazin-1-ylmethyl)phenyl]morpholine as light yellow oil. LCMS (ESI, m/z): 296 [M+H]+.
