실험 절차

4-(6-(methylthio)pyrimidin-4-yl)-1H-pyrazole-3,5-diamine (1.0 g, 4.5 mmol) was combined with 3-ethoxy-2-methylacrylaldehyde (0.63 g, 5.3 mmol) in isopropanol (12 mL). Acetic acid (0.1 mL) was added to the reaction mixture which was then sealed in a microwave vessel and heated to 160° C. for 15 min. The reaction mixture was diluted with ethyl acetate (200 mL) and 1N NaOH (60 mL), the layers separated and the organic layer concentrated to 60 mL. This solution was cooled to 0° C. and 77% m-chloroperbenzoic acid (1.9 g, 8.5 mmol) was added. After 1 hr. a yellow precipitate formed which was filter off, washed with ethyl acetate and dried to give the product, 0.39 g, 30% yield. LCMS MH+289.29. H NMR (500 MHz, DMSO-d6) 9.02 (s, 1H) 8.91 (s, 1H), 8.88 (s, 1H), 8.54 (s, 1H), 7.14 (s, 2H), 2.91 (s, 3H), 2.34 (s, 3H).
