Uses
A substrate used in a microwave-assisted, palladium-catalyzed arylation of acetone as its TMS enol ether.
Application
Methyl 5-bromonicotinate could be used to synthesize Pyridine alkaloids from Rubiaceae with various organometallic reagents by palladium-catalyzed cross-coupling reactions. This compound is a derivative of 5-bromonicotinic acid (BrnicH) which has been widely used in the last decade to obtain MOF materials with unique luminescence, magnetism, catalysis, and adsorption through assembling with lanthanide ions and transition metal ions, such as Cu(II), Co(II), Cd(II), Zn(II), and Pb(II)[1-2].
Synthesis
To an ice-cooled suspension of 5-bromo nicotinic acid (1.6g, 7.9 mmol) in diethyl ether (20ml), a solution of diazomethane in diethyl ether was added dropwise with stirring until the mixture remained yellow. The mixture was stirred for additional 15min (hood!), and the volatile compounds were removed by distillation in vaeuo. Finally, Methyl 5-bromonicotinate was obtained after purification[2].
