反応手順
Methyl iodide (66 g; 0.46 mol) is added drop wise at 0° C. to a solution of thiophene-2-carbothioamide (50 g; 0.33 mol) in 500 ml of acetone. After the addition, stirring is maintained for two hours at 23° C. The precipitate formed is filtered on frit and washed twice with 100 ml of acetone before being dried under vacuum (in a bell jar). A yellow powder is obtained with a yield of 97%.
