Reaction Steps

To a solution of 1-[2-(2,1,3-Benzoxadiazol-5-yl)ethyl]piperazin-2-one (20 mg, 0.081 mmol) in DMF (1 mL) was added 1-(2-Iodoethyl)-4-nitrobenzene (27 mg, 0.097 mmol) and K2CO3 (45 mg, 0.32 mmol). The mixture was allowed to stir at RT for 16 hours. LC showed product formation. The desired product was purified by mass-directed reverse phase HPLC (AcCN-Water with 0.1% TFA). LC-MS (IE, m/z): 396 [M+1]+.
