Yield:98997-63-8 88%
Reaction Conditions:
with potassium hydroxide in water at 20 - 100;
Steps:
Synthesis of 5-azoniaspiro|"4.4"|nonane chloride:
0.02 mol of KOH in 15 mL water were kept under stirring at 100 °C for 10 min, then 0.02 mol of pyrrolidine were slowly added to the mixture at the same temperature and, after 5 min, 0.02 mol of 1,4-dichlorobutane were slowly added. The solution was kept at 100 °C for 18 h, then 1 night at room temperature. The solvent was eliminated under reduced pressure, obtaining a solid, which was dissolved in CHCI3 and filtrated. The chloroform phase was concentrated under vacuum, obtaining 2.84 g of pure 5-azoniaspiro[4.4]nonane chloride (88%).
