Reaction Steps

To the solution of 2-(thiophen-2-yl)pyrimidin-4-ol (100 mg, 0.56 mmol) in HOAc (3 mL) was added NCS (90 mg, 0.67 mmol, 1.2 equiv.) portionwise. The reaction mixture was stirred at 60° C. for 4 h and partitioned between brine and ethylacetate. The organic layer was washed with saturated NaHCO3, brine, dried over Na2SO4, filtered and concentrated. The residue was purified by flash column chromatography to give 5-chloro-2-(thiophen-2-yl)pyrimidin-4-ol (90 mg, 75%). LC-MS (m/z)=213.0 [M+H]+.
