Dimethylamine → 2-Chloro-N,N-dimethylpyrimidin-4-amine

참여 물질

반응 단계

2,4-dichloropyrimidine (104, 500 mg, 3.30 mmol) was dissolved in methanol (5 mL) having 2.0 M dimethylamine dissolved therein, stirred at room temperature for 3 hours. Then, the methanol solvent was removed under reduced pressure and water was added to the reaction mixture. Organic compounds were extracted with ethyl acetate, and the recovered organic solution was washed with a saturated aqueous solution of sodium chloride and evaporated after a treatment with sodium sulfate. Purification was performed by column chromatograph to give the target compound 2-chloro-4-(N,N-dimethylamino)pyrimidine (106c, 426 mg, 80%) as a white solid.
