Hydrogen Sulfide → HCID 85906196, compound

Participants

Reaction Steps

A stirred mixture of 141 g of 3-amino-2-cyano-3-propoxypropenenitrile and 94.4 g of triethylamine in 250 ml of pyridine was heated at 80° for 4 hours while hydrogen sulfide gas was continually passed through the mixture. Thin-layer chromatography indicated reaction to be complete. The reaction mixture was diluted to 2 liters with water and the pale yellow precipitate was collected by filtration. The precipitate was recrystallized from ethanol to give 114 g of 3-amino- 2-cyano-3-propoxypropenethioamide, mp 174°.
