Participants

Reaction Steps

A suspension of 2.63 parts of 1-t-butyl-3(-3-thioxo-3H-1,2,4-dithiazol-5-yl)urea and 1.42 parts of methyl iodide in 50 parts of tetrahydrofuran was stirred for 1 hour at room temperature and refluxed with stirring for 1 hour. After cooling to room temperature 3.0 parts of triethylamine and 1.0 parts of N-methyl piperazine were added to the suspension and the mixture was stirred at room temperature overnight. The mixture was filtered to remove triethylamine hydroiodide and the solvent was removed from the filtrate under reduced pressure. The filtrate residue was triturated with water and recrystallized from methanol to afford 1.0 part of the title compound, m.p. 169°-172°.
