Reaction Steps

A mixture of (Z)-5-((4-(cyclopropylamino)-2-(methylsulfinyl)pyrazolo[1,5-a][1,3,5]triazin-8-yl)methylene)imidazolidine-2,4-dione and (Z)-5-((4-(cyclopropylamino)-2-(methylsulfonyl)pyrazolo[1,5-a][1,3,5]triazin-8-yl)methylene)imidazolidine-2,4-dione (20 mg, 0.056 mmol) was mixed with 1H-imidazole-4-carbaldehyde (16 mg, 0.168 mmol) in isopropanol (2 mL). The mixture was stirred under microwave heating at 150° C. for 20 minutes. The reaction mixture was cooled to room temperature and the solvent was removed by rotary evaporation to provide (Z)-1-(4-(cyclopropylamino)-8-((2,5-dioxoimidazolidin-4-ylidene)methyl)pyrazolo[1,5-a][1,3,5]triazin-2-yl)-1H-imidazole-4-carbaldehyde as a crude mixture which was taken on to the next step without further purification. LCMS (ES): >95% pure, m/z 380 [M+H]+
