Procedure

50 g (0.29 mol) of 3-methyl-2,4-dicyanothiophenol were added to a solution of 23 g (0.58 mol) of NaOH in 400 ml of water, and 73 g (0.58 mol) of dimethyl sulfate were then added dropwise at 25-35° C. The mixture was stirred at 25° C. for 16 h, after which a solid had precipitated out, which was filtered off with suction, washed twice with water and then recrystallized from glacial acetic acid/water. Yield: 43 g (80%).
