Related Products of 870997-85-6, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.870997-85-6, name is 3-Amino-5-bromopyridine-2-carboxylic Acid, molecular formula is C6H5BrN2O2, molecular weight is 217.0201, as common compound, the synthetic route is as follows.
Step 1: 3-Amino-5-(4-trifluoromethoxy-phenylsulfanyl)-pyridine-2-carboxylic acid: [00273] A solution of 3-amino-5-bromo-pyridine-2-carboxylic acid (Int 1, 3.26 g, 15 mmol), 4- trifluoromethoxy-benzenethiol (CAS: 169685-29-4, 3.5 g, 18 mmol) and DBU (2.22 mL, 15 mmol) was prepared in DMA (15 mL). This mixture was heated at 140 C for 45 minutes in a microwave reactor. Next, the mixture was diluted with a mixture of 1% AcOH in water. A suspension was obtained that was subsequently filtered. This collected solid was washed with a 101 ABV12212USO1 1% AcOH/water mixture followed by washing with petroleum ether. After drying in a vacuum oven, the titled compound was obtained
The chemical industry reduces the impact on the environment during synthesis 870997-85-6, I believe this compound will play a more active role in future production and life.
