Reaction Steps

Under argon, 280 mg (0.79 mmol) of 2-dimethylamino-4-phenyl-6-phenylsulfanyl-3,5-pyridinedicarbonitrile (step 2) are dissolved in 3 ml of abs. dimethylformamide (DMF), and 204 mg (2.6 mmol) of sodium sulfide are added. The reaction mixture is stirred at 80° C. for 2 hours. 6 ml of 1 N hydrochloric acid are added to the mixture and the resulting yellow crystals are filtered off with suction, washed with water and petroleum ether/diethyl ether 1/1 and dried under reduced pressure overnight.
