実験手順
To a solution of 1-[2-(4-nitrophenyl)ethyl]piperazine hydrochloride (30 mg, 0.11 mmol) in DMF (2 mL) was added 1-(2-bromoethyl)-4-nitrobenzene (31 mg, 1.3 mmol) and TEA (46 uL, 0.33 mmol). The mixture was heated to 80° C. for 16 hours. LC showed some desired product at that point. The desired 1,4-bis[2-(4-nitrophenyl)ethyl]piperazine was purified by mass-directed HPLC. LC-MS (IE, m/z): 385 [M+1]+. (0.052 μM)
