Procedure

To a solution of potasium hydroxide (1.5 g) in methanol (11 ml) was added 3-[4-(2-hydroxyethyl)-1-piperazinyl]propylamine (5.0 g) and thereto was added carbon disulfide (2.0 g) under ice cooling over a perod 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 (10 ml), washed with diethyl ether. The washed aqueous layer was ice-cooled and thereto was added methyl iodide (3.8 g) with stirring. The resulting mixture was stirred for 2 hours under ice-cooling, extracted with ethyl acetate, dried over magnesium sulfate and then evaporated to give methyl-N-[3-[4-(2-hydroxy-ethyl)-1-piperazinyl]propyl]dithio-carbamate (4.8 g).
