Reaction Conditions

Reaction Steps

42 g (0.2 mol) of 1,4-dihydroxy-2,3-dicyanonaphthalene and 200 ml of N,N-dimethylformamide (DMF) were introduced at room temperature as the initial charge. 55.4 g (0.44 mol) of dimethyl sulfate and 60.8 g (0.44 mol) of potassium carbonate were added. The batch was slowly heated to 100° C. and stirred at that temperature for 8 h. It was then poured onto water, and the resulting precipitate was filtered off with suction, washed With water and dried to leave 30 g of 1,4-dimethoxy-2,3-dicyanonaphthalene (theory: 64%; melting point: 190° C.).
