Reaction Steps

Stir the mixture of 1-(chloromethyl)-3-nitro-5-(trifluoromethyl)benzene (640 mg, 2.68 mmol) and N-methylpiperazine (536 mg, 5.36 mmol) in THF (8 mL) for 2 hrs at 60° C. TLC (EtOAc:PE=1:1) shows the reaction is complete. Concentrate the reaction mixture under reduced pressure to obtain the crude product (812 mg, 100%). MS: (M+1): 303.1.
