A 2-neck 250 mL round bottom flask was equipped with a gas inlet adapter and a gas outlet attached to two traps in series, the first trap being empty and the second trap containing water. The reaction vessel was charged with 2,4-dichloro-5-(2-(methylthio)phenyl)pyrimidine and carbon tetrachloride (49.8 ml) and heated to reflux to dissolve the 2,4-dichloro-5-(2-(methylthio)phenyl)pyrimidine, then cooled to room temperature creating a clear colorless solution. Chlorine gas was bubbled through the reaction solution while stirring vigorously creating a clear yellow solution. The reaction was monitored by direct NMR of aliquots diluted in DMSO-d6. Upon completion the reaction solution was concentrated in vacuo yielding 14.7 g (99% yield) of 2,4-dichloro-5-(2-((trichloromethyl)thio)phenyl)pyrimidine as yellow solids.
