Reaction Steps

10 g of dimethylamine hydrochloride are placed in 60 ml of water, a nitrogen atmosphere is applied and the solution is cooled to between 0° C. and −5° C., and then 18 ml of 3-chloro-1-propanesulphonyl chloride are added dropwise. 10.6 g of sodium hydroxide in 40 ml of water are added while maintaining at −5° C., then the mixture is allowed to return to AT and stirring is maintained for 1 hour. 1 ml of concentrated HCl is added and then extraction is carried out with DCM. The organic phase is washed with a 10% NaOH solution and then with an NaCl solution. 15.1 g of the expected compound are obtained.
