Reaction Steps

TEA (0.23 ml) and benzenesulfonyl chloride (0.075 ml) were added to a dichloromethane (5 ml) solution containing 3-pyridyl 1-piperazinecarboxylate dihydrochloride (150 mg), followed by stirring overnight at room temperature. The reaction solution was diluted with chloroform, the organic layer was washed with aqueous saturated sodium hydrogencarbonate solution, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, the residue was purified by silica gel column chromatography (eluent: chloroform), and the resulting solid was recrystallized from 2-propanol to obtain 3-pyridyl 4-(phenylsulfonyl)-1-piperazinecarboxylate (130 mg).
