Reaction Steps

A solution of the 5butyl-2-chloro-4-methyl-6-phenyl-pyrimidine (215 mg, 0.825 mmol) and Br2 (0.042 ml, 0.825 mmol) in AcOH (2 mL) is stirred at 80° C. for 21 hours. After cooling, the solution is concentrated. The residue is partitioned between Et2O and half saturated aqueous NaHCO3. The layers are separated, and the aqueous layer is reextracted once with Et2O. The combined extracts are dried over Na2SO4 and concentrated to 305 mg of crude 4-bromomethyl-5-butyl-2-chloro-6-phenyl-pyrimidine, which also contains small amounts of SM and dibromo material. This material is used without further purification.
