Reaction Steps

Under argon, 400 mg (10.0 mmol) of sodium hydride (60% suspension in oil) are suspended at room temperature in 40 ml of THF. A solution of 661 mg (10.0 mmol) of malonodinitrile in 10 ml of THF is added dropwise, and the reaction mixture is stirred for 15 min. A solution of 891 mg (5.0 mmol) of 2-methyl-5-methylsulphonyl-1,3,4-thiadiazole in 10 ml of THF is added dropwise. The reaction mixture is heated to 50° C. and stirred overnight, cooled and concentrated using a rotary evaporator. The residue is dissolved in water and adjusted to pH=3 using HCl. A brown solid precipitates out, and this solid is filtered off and dried under reduced pressure.
