Reaction Steps
A solution of dimethyl cyanodithioimidocarbonate (16.0 g; 0.109 mole) and propargylamine (6.03 g; 0.109 mole) in acetonitrile (320 ml) was stirred at reflux for 4 hours, then at ambient temperature for 12 hours. Workup gave 13.58 g (85%) of N-cyano-N'-(2-propyn-1-yl)-S-methylisothiourea; mp 160°-164°.
