Product Name:5-Bromo-2-methylpyridine
CAS Number:3430-13-5
Molecular formula:C6H6BrN
Molecular Weight:172.02

5-Bromo-2-methylpyridine can be used as a pharmaceutical intermediate in the production of cardiovascular and cerebrovascular drugs. Its synthesis method is that the mixtrue of diethyl malonate and sodium hydrogen was stirred for 1h, add 5-nitro-2-chloropyridine in toluene and react for 1.5h at 110℃, then stirred for 15h at RT, and purify to obtain 5-nitro-2-methylmethane pyridine, 94%.
