Reaction Conditions

Reaction Steps

N-decylpiperidine was synthesized by reacting 45.7 g piperidine with 118.7 g 1-bromodecane in 237 mL acetone in the presence of 74 g potassium carbonate. After refluxing this reaction mixture at 55° C. for 24 hr, it was filtered and acetone was removed from the filtrate to yield 61 g N-decylpiperidine. 5 g N-decylpiperidine and 42 g 1-bromo-3-chloropropane were dissolved in 50 mL methanol and the reaction mixture was heated at 65° C. for 18 hr. After cooling to room temperature, methanol was removed under reduced pressure. The residue was poured into 2 L tert butylmethyl ether with stirring and then the mixture was allowed to stand for 6 hr. The white precipitate thus formed was filtered and was dried at 40° C. under vacuum for 24 hr yielding 68 g (3-chloropropyl)decylpiperidinium bromide as a light yellow solid.
