Reaction Steps
A mixture of 5-chloro-2-(thiophen-2-yl)pyrimidin-4-ol (90 mg, 0.42 mmol, 1.0 equiv.), POBr3 (364 mg, 1.27 mmol, 3.0 equiv.) and N,N-dimethylbenzenamine (103 mg, 0.85 mmol, 2.0 equiv.) in toluene (5 mL) was stirred at 100° C. for 1 h, then poured into crashed ice. The mixture was extracted with ethyl acetate. The combined organic layers were washed over saturated NaHCO3, brine, dried over Na2SO4, filtered and concentrated. The residue was purified by column chromatography to afford 4-bromo-5-chloro-2-(thiophen-2-yl)pyrimidine, which was directly used for the next step. LC-MS (m/z)=275.0 [M+H]+.
