Phosphorus oxychloride → 2-Butylsulfanyl-4-chloro-pyrimidine

참여 물질

반응 단계

A mixture of 2-butylsulfanyl-3H-pyrimidin-4-one (3.0 g) and phosphorus oxychloride (15 mL) was heated at reflux for 3 h; it was then cooled to RT and evaporated under reduced pressure. The residue was poured into an ice-water mixture, and the resulting mixture was extracted with DCM. The combined organic extracts were washed with a diluted aqueous solution of NaHCO3, dried over Na2SO4, filtered and evaporated under reduced pressure to give 1.2 g of 2-butylsulfanyl-4-chloro-pyrimidine.
