反応手順

17 ml of cold borontrifluoride etherate was added to a suspension of 7 g of 2-methoxy-1,4-anthraquinone in 120 ml of isopropanol. The reaction was carried at 70°-80° C. overnight. After partially concentrated, the reaction mixture was left at room temperature and the crude product was obtained as dark brown precipitate. Recrystallization from isopropanol yielded 5 g of pure yellow needles of IPAQ.
