Reaction Steps

Following the procedure of Partyka and Crenshaw in U.S. Pat. No. 4,001,238, a solution of ethyl-1,3,4-oxadiazole-2-thione-5-carboxylate potassium salt dimethylsulfoxide solvate (4.1 g, 24 mmol) and iodomethane (6.7 g, 47 mmol) are heated for 1 hour at reflux in EtOH (20 mL). A solid is removed by vacuum filtration, and the filtrate is concentrated. Water (40 mL) is added to the resultant material, a solid is isolated by vacuum filtration, dried at 50° C./0.5 mmHg overnight to afford the desired product (2.3 g, 50%).
