Participants

Reaction Steps

A suspension of 4.75 parts of the hydrobromide salt of 3-imino-5-dimethylamino-3H-1,2,4-dithiazole, two parts of t-butyl isocyanate, two parts of triethylamine, and 50 parts of tetrahydrofuran was stirred and refluxed for two days. The reaction mixture was cooled and the insoluble triethylammonium bromide was removed by filtration and discarded. The filtrate was then evaporated under reduced pressure leaving a white solid, which was recrystallized from isopropanol to afford 3.4 parts of 1-t-butyl-3-(5-dimethylamino-3H-1,2,4-dithiazol-3-ylidene)urea, m.p. 174°-177°C. dec.
