Reaction Steps

A 100 mL round-bottom flask was charged with tert-butyl 4-[[5-chloro-2-(pyrrolidin-1-yl)phenyl]methyl]piperazine-1-carboxylate (500 mg, 1.32 mmol, 1.00 equiv), dichloromethane (10 mL). The mixture was cooled to 0° C. Trifluoroacetic acid (1 mL) was added dropwise at 0° C. The resulting solution was stirred overnight at room temperature. The resulting mixture was concentrated under reduced pressure to yield 490 mg (crude) of 1-[[5-chloro-2-(pyrrolidin-1-yl)phenyl]methyl]piperazine as a brown solid. LCMS (ESI, m/z): 280 [M+H]+.
