Reaction Steps

N-decylpiperidine was synthesized by reacting 45.7 g of piperidine with 118.7 g of 1-bromodecane in 237 mL of acetone in the presence of 74 g of 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 of N-decylpiperidine. N-decylpiperidine (5 g) and 42 g of 1-bromo-3-chloropropane were dissolved in 50 mL of methanol and the reaction mixture was heated to 65° C. for 18 hr. After cooling to room temperature, methanol was removed under reduced pressure. The residue was poured into 2 L of tert-butylmethyl ether with stirring and then the mixture was allowed to stand for 6 hr. The white precipitate was collected by filtered and was dried at 400 C under vacuum for 24 hr yielding 68 g of (3-chloropropyl)decylpiperidinium bromide as a light yellow solid.
