Reaction Steps

A solution of NaOH (40 g, 999 mmol) in H2O (40 mL) was slowly added via an addition funnel such that the internal temperature did not exceed 10° C. to a cold (0° C.) solution of ethyl 2-cyanoacetate (53.3 mL, 499.5 mmol) and carbon disulfide (30.2 mL, 499.5 mmol) in absolute EtOH (600 mL) Once the addition was complete, the reaction mixture was allowed to stir at room temperature for 10 minutes. The reaction mixture was then cooled to 5° C. The resulting solids were isolated by filtration and washed with EtOH (100 mL), ether (500 mL) and dried in vacuo to give sodium 2-cyano-3-ethoxy-3-oxoprop-1-ene-1,1-bis(thiolate) (110.0 g, 97%) as a solid.
