Related Products of 849068-61-7 ,Some common heterocyclic compound, 849068-61-7, molecular formula is C8H5BrN2O2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.

To a mixture of 5-bromo-1H-pyrrolo[2,3-b]pyridine-3-carboxylic acid (20 g, 82.99 mmol) in MeOH (200 mL) was added SOCl2 (30ml) dropwise at room temperature. After addition, the resulting mixture was heated to 70 C and stirred overnight. TLC (EtOAc) showed the reaction was completed. The solvent was removed in vacuo and then aqueous NaHCO3 (20 mL) was added at which time a precipitate formed. The solid was filtered and dried to give methyl 5-bromo-1H-pyrrolo[2,3-b]pyridine-3- carboxylate (15.3g, 72.3%) as a brown solid.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,849068-61-7, its application will become more common.
