| Introduction | 3-hydroxy-2-methylpyridine is a pharmaceutical intermediate, which can be prepared by one-step reaction of 2-acetylfuran and ammonia. 3-hydroxy-2-methylpyridine can be prepared with N-bromosuccinimide to prepare 2, 4-dibromo-3-hydroxy-6-methylpyridine, and then further react to prepare 2-bromo-5-hydroxy-6-methylpyridine. |
| Uses | 3-hydroxy-2-methylpyridine is used for the preparation of substituted pyridine and pyrimidine derivatives and its use in the treatment of viral infections. |
| application | 3-hydroxy-2-methylpyridine can be used as a chemical and pharmaceutical intermediate, which can be used in laboratory research and development and chemical and pharmaceutical synthesis. |
| preparation | 0.03mol of 2-acetylfuran, 35mL of methanol, a certain amount of ammonium salt and 20.4g of 25% ammonia water are put into a 100 mL customized high-temperature digestion tank, stirred by magnetic force, and reacted at an oil bath temperature of 170 ℃ for 16h. After the reaction is completed, filtration, decolorizing the filtrate with activated carbon for 3 times, spinning off the solvent to obtain gray solid, 50% recrystallization and purification in ethanol water. 2-methyl -3-hydroxypyridine, melting point 167~171 ℃, molar yield 33.2%. |
| Biological activity | 3-Hydroxy-2-methylpyridine It is isolated from theobromine extract and can be used for the synthesis of pyrimidine. |
