Versuchsvorschrift

To a solution of 1.00 g (2-cyano-3,3-bis(methylthio)acrylamide) in 25 mL of ethanol was added 0.720 g (1.1 eq.) of N,N-dimethyl-p-phenylenediamine and the reaction was stirred at 75° C. until starting amide was absent as confirmed by HPLC. Once complete (18 hrs), the reaction was brought to room temperature and filtered to obtain 2-cyano-3-((4-(dimethylamino)phenyl)amino)-3-(methylthio)acrylamide as an off white to light yellow powder. The product was allowed to dry under vacuum for 1 hr (1.133 g, 91% yield).
