Participants

Reaction Steps

Sodium hydroxide (130 μL of a 3N aqueous solution) was added to a solution of 1,10-bis[(4-chlorophenyl)sulfonyl]-4,5,6,7,8,9-hexahydro-1H-4,8-epiminocycloocta[c]pyrazole-6-carbonitrile and 2,10-bis[(4-chlorophenyl)sulfonyl]-4,5,6,7,8,9-hexahydro-2H-4,8-epiminocycloocta[c]pyrazole-6-carbonitrile (61) (69 mg, 0.13 mmol) in THF (0.5 mL) and the resulting solution was stirred at room temperature for 5 h. The reaction mixture was diluted with EtOAc and washed with brine. The organic phase was dried (Na2SO4), filtered, concentrated and purified by preparative HPLC to give 10-[(4-chlorophenyl)sulfonyl]-4,5,6,7,8,9-hexahydro-1H-4,8-epiminocycloocta[c]pyrazole-6-carbonitrile (62).
