2-(Bis(methylsulfanyl)methylidene)propanedinitrile → HCID 19610562, compound

Participants

Reaction Steps

A mixture of 13.89 g (81.58 mmol) of 3,3-bis-methylmercapto-2-cyano-acrylonitrile, 17 g (81.63 mmol) of N-BOC-1,4-phenylenediamine (Fluka) and 200 ml of methanol is heated under reflux for 5 hours. Cooling to room temperature, filtering and washing the filter residue with methanol yield the title compound; m.p. 190° C. Concentration of the filtrate by evaporation and recrystallization of the residue from 50 ml of methanol yield a further batch of the title compound; m.p. 190-191° C.
