Procedure

To a solution of potassium hydroxide (6.3 g) in methanol (40 m) was added 3-(4-allyl-1-piperazinyl)propylamine (18.8 g) and thereto was added carbon disulfide (7.8 g) under ice cooling over a period of 10 minutes. The resulting mixture was stirred for 2 hours under ice cooling. The reaction mixture was evaporated under reduced pressure. The residual oil was dissolved in water and washed with diethyl ether. The washed aqueous layer was ice-cooled and thereto was added methyl iodide (14.6 g) with stirring. The resulting mixture was stirred for 2 hours under ice-cooling. The reaction mixture was extracted with ethyl acetates, the extract was washed with a saturated aqueous solution of sodium chloride, dried over magnesium sulfate and then evaporated under reduced pressure to give an oil of methyl N-[3-(4-allyl-1-piperazinyl)propyl]dithiocarbamate (17.7 g).
