Sodium Carbonate → 4-[(8aR)-hexahydropyrrolo[1,2-a]pyrazin-2(1H)-ylcarbonyl]benzenesulfonyl chloride

참여 물질

반응 단계

To 4-(chlorosulfonyl)benzoyl chloride (3 mmol) in anhydrous dichloromethane (100 mL) was slowly added over 10 minutes (R)-octahydropyrrolo[1,2-a]pyrazine (0.379 g, 3 mmol) at room temperature in dichloromethane (4 mL). Then sodium carbonate (0.954 g, 9 mmol) was added. The mixture was stirred at room temperature overnight. Then the reaction mixture was concentrated to provide 4-[(8aR)-hexahydropyrrolo[1,2-a]pyrazin-2(1H)-ylcarbonyl]benzenesulfonyl chloride which was used without additional purification.
