| Hazard Information | Back Directory | [Uses]
Design and synthesis of potent, selective, and orally bioavailable tetrasubstituted imidazole inhibitors of p38 mitogen-activated protein kinase 4-(Bromoacetyl)pyridine hydrobromide was used to prepare 2-Phenyl-4-(4-pyridyl)imidazole. | [Synthesis]
General procedure for the synthesis of 4-(bromoacetyl)pyridine hydrobromide from 4-acetylpyridine: 558 g of batch master batch was added to a reaction flask, followed by the addition of 42 g of ethyl acetate, and 121.1 g of 4-acetylpyridine was added slowly with stirring, keeping the reaction temperature at 20~30 °C and stirring well. N-bromosuccinimide (NBS) 186.9 g was added in batches, followed by slow warming to 65~75 °C. The progress of the reaction was monitored by thin layer chromatography (TLC) until the feedstock was fully reacted. After completion of the reaction, the reaction mixture was cooled to 0~10°C to allow complete crystallization of the product. The crystals were collected by filtration, washed and pulped with 650 g of deionized water, filtered again, and dried to give 275.6 g of 4-(bromoacetyl)pyridine hydrobromide as a white solid in 98.1% molar yield. | [References]
