Piperidine, 1-(3-chloropropyl)-, hydrochloride (1:1) Use and Manufacturing

Reference Example 10 1.72 g (20.3 mmol) of piperidine, 2 ml (24.3 mmol) of 3-chloropropanol and 10 ml toluene were added successively into a reaction flask. The mixture was heated to the reflux temperature and reacted for 4 h. Into the reaction mixture, 5percent NaOH 4 ml was added, and the mixture was refluxed for 1 h. After cooling to room temperature, the mixture was washed with 5percent NaOH solution. The organic layer was washed with a saturated saline solution, then dried over anhydrous sodium sulfate and filtrated. 3 ml (40.6 mmol) thionyl chloride was added dropwise into the filtrate in an ice-bath, and the mixture was stirred at room temperature overnight. The reaction solution was concentrated to dry in a reduced pressure, and the residue was recrystallized with absolute ethyl alcohol to obtain 2.4 g of a khaki solid with the yield of 59percent. m.p. 218-220° C.
