4-Fluorobenzenesulfonyl chloride → 1-(4-Fluorobenzenesulfonyl)pyrrolidine

Participants

Reaction Steps

To a solution of pyrolidine (17 mL, 237 mmol) in 20 mL of H2O at room temperature was added p-flourobenzenesulfonyl chloride (15 g, 79 mmol) in portions over a 5 minute period. After 1 hour, the solution was diluted with 100 mL of H2O and extracted with ethyl acetate (3×50 mL). The organic was dried (Na2SO4) and concentrated in vacuo to give 12.3 g (72%) of 4-(pyrrolidinosulfonyl)-flourobenzene as a colorless oil that solidified on standing. This material was used in the following reaction without further purification. MS.
