참여 물질

반응 단계

To a stirred suspension of 5-(4,6-dichloro-[1,3,5]triazin-2-ylamino)-3-methyl-imidazolidine-2,4-dione (Example 1.3, Part D) (200 mg, 0.72 mmol) and potassium carbonate (219 mg, 1.59 mmol) in dimethylformamide (5 mL) at room temperature was added 4-methyl-benzylamine (0.1 mL, 0.79 mmol). The reaction mixture was stirred at 35° for 24 h and then diluted with water and ethyl acetate. The ethyl acetate layer was separated, dried and evaporated to give the crude product which was used directly in the next step.
