150-78-7, The chemical industry reduces the impact on the environment during synthesis 150-78-7, name is 1,4-Dimethoxybenzene, I believe this compound will play a more active role in future production and life.
To a solution of 1,4- dimethoxybenzene Q-8 (7.5 g, 53.57 mmol) in acetic acid (25 mL) was added a solution of bromine (17.4 g, 108.9 mmol) in acetic acid (5 mL) at room temperature. After stirring for 2h, the solution was cooled to 10 0C. The resulting fine precipitate was filtered, washed with water (20 mL), and dried under vacuum to obtain compound Q-9 (1Og, 63%) as a white solid. TLC Rf = 0.5 (petroleum ether – EtOAc, 9.9:0.1); 1H NMR (CDCl3) delta 7.10 (s, 2H), 3.84 (s, 6H).
