Reaction Steps

11.6 g (100 mmol) of 2-chloroethylamine HCl were suspended in dichloromethane. 13.8 g (175 mmol) of pyridine were added, the mixture was stirred for 10 minutes and then 15.8 g (75 mmol) of 4-chlorobenzenesulfonyl chloride, dissolved in dichloro-methane, were added dropwise. The reaction mixture was heated under reflux for 8-10 hours, then treated with water and adjusted to a pH of 1-2 using HCl. The organic phase was washed three times with 3% strength HCl and the aqueous phase was extracted by shaking 3-4 times with dichloromethane. The combined organic phases were dried using Na2SO4, evaporated in the and recrystallized from ethanol. The yield was 11 g.
