실험 절차

5-(5-Chloro-2-(methylthio)pyrimidin-4-yl)-N-(4-fluorophenyl)-1,3,4-thiadiazol-2-amine (0.637 g, 1.7 mmol) was dissolved in 300 mL acetone. Oxone (6.3 g, 10.3 mmol) was dissolved in 300 mL H2O and added in one portion to the acetone solution and allowed to stir overnight at room temperature. The acetone was removed under vacuum, the resulting precipitate was obtained by filtration. LC/MS analysis indicates a mixture of both sulfoxide and sulfone. This solid mixture was dried briefly in a vacuum oven. This material was charged to a microwave reaction vessel along with 1-(2-aminoethyl)-5,5-dimethyl-imidazolidine-2,4-dione (0.588 g, 3.4 mmol), diisopropyl ethylamine (0.60 mL, 3.4 mmol) and 15 mL IPA. This reaction was heated under microwave conditions to 170° C. for 1200 s. Upon cooling 0.545 g (67% yield) of product was obtained by filtration. MS (M+H)+ 477.
