Procedure

6-Amino-5-((E)-2-bromovinyl)-2-(4-chloro-2-fluoro-3-methoxy-phenyl)pyrimidine-4-carboxylic acid methyl ester (0.915 g, 2.196 mmol) was dissolved in DMSO (10 mL) and sodium thiomethoxide (0.169 g, 2.416 mmol) was added. After 30 min at ambient temperature, the reaction mixture was diluted with water and extracted with ethyl acetate. The organic phase was diluted with petroleum ether to decrease the solubility of residual DMSO, washed with water thrice, filtered and concentrated. The product was purified by flash chromatography (hexane/ethyl acetate gradient) to provide the title compound (0.510 g, 60.5% yield) as a yellow solid: 1H NMR (CDCl3) δ 7.63 (dd, 1H), 7.19 (dd, 1H), 6.74 (d, 1H), 6.32 (d, 1H), 5.34 (br s, 2H), 3.99 (d, 3H), 3.94 (s, 3H), 2.41 (s, 3H).
