Reaction Steps

To a mixture of 4-(3,4-dichlorophenyl)piperazine (350 mg, 1.51 mmol), cis-3-(N-Boc-amino)cyclohexane carboxylic acid (368 mg, 1.51 mmol), HOBt (209 mg, 1.51 mmol) and EDC (291 mg, 1.51 mmol) was added dichloromethane followed by TEA (153 mg, 1.51 mmoL). Upon completion of addition, the resulting solution was allowed to stir overnight. At the conclusion of this period, the reaction mixture was concentrated and then purified via silica gel chromatography (20% to 50% EtOAc/hexanes) to provide the title compound (640 mg) as an oil.
