반응 단계
50.0 g of 3,4-dimethoxy-nitrostyrene (compound J1), and 1.0 g (9.1 mmol) of hydroquinone are suspened in 200 ml of abs. toluene and treated at −70° C. with 55.0 g (1.02 mol) of liquid 1,3-butadiene. The mixture is stirred at 160° C. for 6 days in an autoclave and then cooled. Some of the solvent is removed on a rotary evaporator, and the resulting precipitate is filtered off with suction and recrystallized in ethanol. M.p.: 113.5-115.5° C.
