Reaction Steps

Dissolved malononitrile (5.0 g) in DMF (50 mL), added triethylamine (1 eq., 10.49 mL), and stirred for 5 minutes before adding phenylisothiocyanate (1 eq) dropwise, then stirred until complete by TLC (absence of phenylisothiocyanate, 3 hrs). Added methyl iodide (1 eq) dropwise, then stirred until intermediate was fully consumed (absent on TLC, 18 hrs); poured into 100 mL ice water, then filtered resulting solution to obtain 2-((methylthio)(phenylamino)methylene)malononitrile as a white powder.
