Reference of 141215-32-9, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 141215-32-9 name is 4,7-Dibromobenzo[c][1,2,5]thiadiazole-5,6-diamine, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
Dissolve 5,6-diamino-4,7-dibromobenzo [c] [1,2,5] thiadiazole (0.38g, 1.2mmol) in anhydrous chloroform (10mL) round bottom In a flask, the mixture was stirred with thionyl chloride (1.2 mL) at 0 C, then 8.0 mL of pyridine was added, and the reaction was carried out at room temperature for 20 hours. After the reaction, the mixture was cooled to room temperature and sucked onto ice water, and the precipitate was filtered and methanol was washed with water to obtain a core.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 4,7-Dibromobenzo[c][1,2,5]thiadiazole-5,6-diamine, and friends who are interested can also refer to it.
