实验过程

To a mixture of 3-amino-4-fluorophenyl 3-methyl-2-pyridyl ketone(4.20 g, 0.171 mol), sodium thiocyanate (4.19 g, 0.0517 mol) and glacial acetic acid is added a solution of bromine in acetic acid (2M, 12 ml, 0.0240 mol) over a one hour period. The resultant mixture is stirred one hour at room temperature and poured into cold water. The precipitate is filtered and dried to afford the title compound as a green solid (5.43 g, >100%) which is identified by NMR and mass spectral analysis.
