Procedure

N-methyl piperizine (4.68 g) was dissolved in isopropanol (25 ml) and treated with 1,3-propanesultone (5.7 g) with cooling to maintain the temperature of the reaction below 50° C. The reaction mixture was allowed to stand at room temperature overnight, then diluted with ether and the white solid filtered. On standing, the white solid became a sticky semi-solid (7.1 g).
