YieldReaction ConditionsOperation in experiment
96% With trimethylsilyl bromide In acetonitrile at 40℃; for 30 h; Bromo trimethylsilane (23 mL, 174.31 mmol) was addedto a solution of 4-chloro-2-methylsulfanylpyrimidine (2.9 g 25 mmol) inacetonitrile (240 mL).The mixture was stirred for 30 h at 40°C. The reactionwas monitored by TLC. After cooling to room temperature, NaHCO3saturated solution (250 mL) was added and the product was extracted with AcOEt.The organic layer was dried over Na2SO4, filtered, andevaporated under reduced pressure. The crude residue was purified bychromatography on silica gel using dichloromethane-ethyl acetate (9:1).Evaporation of the eluent in vacuum gave the desired compound in 96percent yield(4.66 g) as colorless oil.

YieldReaction ConditionsOperation in experiment
83% With phosphorus(V) oxybromide In acetonitrile at 80℃; for 5 h; To a stirred solution of 2-(methylthio)pyrimidin-4(3H)-one (5 g, 35.21 mmol, leq) in ACN (lOOmL) was added POBr3 (12.1 g, 42.3 mmol, 1.2 eq) at RT, then the reaction mixture was heated to 80°C for 5h. Monitored by TLC, the reaction mixture was cooled to RT and quenched in ice cold water then extracted with EtOAc (2X100mL). The combined organic layer was dried over Na2SC>4 and concentrated to crude compound. The crude compound was purified by column chromatography (silica gel, 100-200 mesh) using 0-10percent EtOAc in pet ether as eluent to afford 4- bromo-2-(methylthio)pyrimidine (6g, 83percent) as off-white solid. LCMS: [M+H]+ 204.9.

YieldReaction ConditionsOperation in experiment
86% at 0 - 20℃; for 3 h; To stirred 30percent H202 (6g, 29.4 mmol, 1 eq) was added ammonium molybdate tetrahydrate (1.09g, 0.88mmol, 0.03eq) at 0°C portion wise then stirred for 20min., and then a solution of 4-bromo-2-(methylthio)pyrimidine (6g, 29.41mmol, leq) slowly added at 0°C then allowed to RT for 3h. Monitored by TLC, the reaction mixture was concentrated to crude residue, which was diluted with cold water then extracted with DCM (3X100mL). The combined organic layer was washed with 5percent H2SC>4 solution and water then dried over Na2SC>4 and concentrated to crude compound. The crude compound was purified by column chromatography (silica gel, 100-200 mesh) using 0-40percent EtOAc in pet ether as eluent to afford 4-bromo-2- (methylsulfonyl)pyrimidine (6g, 86percent) as off-white solid.
