Participants

Conditions

Temperature: 70 °C

Procedure

In 10 ml of chloroform are dissolved 0.48 g of 2-[(2-methoxy-3-octadecyloxypropyl)sulfonyl]ethyldimethylamine and 1 g of methyl methanesulfonate and the solution is stirred at 70° C. for 5 hours. Then the reaction mixture is concentrated under reduced pressure and the residue is crystallized from chloroform and ether to give 417 mg of the captioned compound.
