Reaction Steps

9-Bromo-6,7,8,9-tetrahydrobenzocyclohepten-5-one (590 mg, 2.5 mmol), 1-t-butoxycarbonylpiperazine (500 mg, 2.7 mmol) and potassium carbonate (510 mg, 3.7 mmol) were stirred overnight in DMF. The reaction solution was mixed with water, the reaction product was extracted with ethyl acetate, washed with water and saturated brine and dried with anhydrous sodium sulfate, the solvent was removed by evaporation under a reduced pressure, and the thus obtained material was separated and purified by a silica gel column chromatography to obtain 450 mg (1.3 mmol, 53%) of the title compound.
