Procedure

A (1:1) mixture of (Z)-5-((4-(cyclopropylamino)-2-(methylsulfonyl)pyrazolo[1,5-a][1,3,5]triazin-8-yl)methylene)imidazolidine-2,4-dione and (Z)-5-((4-(cyclopropylamino)-2-(methylsulfinyl)pyrazolo[1,5-a][1,3,5]triazin-8-yl)methylene)imidazolidine-2,4-dione (36 mg) was suspended in NMP (0.2 ml). Cyclopropylmethylamine (88 uL) was added and the mixture stirred at room temperature for 15 minutes. Water and methylene chloride were added and the resulting precipitate was filtered. After triturating in a mixture of ethyl acetate and hexanes, (Z)-5-((4-(cyclopropylamino)-2-(cyclopropylmethylamino)pyrazolo[1,5-a][1,3,5]triazin-8-yl) methylene)imidazolidine-2,4-dione was isolated as a yellow solid.). LCMS (ES):>95% pure, m/z 355 [M+H]+.
