実験手順

4-Chloro-2-(methylthio)pyrazolo[1,5-a][1,3,5]triazine (1.0 eq, 6.26 g, 31.19 mmol) was suspended in anhydrous NMP (50 ml). Cyclopropylamine (1.5 eq, 3.2 ml, 46.26 mmol) was added through syringe dropwise. Internal temperature rose to 47° C. The mixture was stirred without any external cooling for one hour. An additional amount of cypropylamine (1 ml) was added and the mixture stirred for another 1.5 hours. The mixture was slowly poured into water (500 ml) under stirring. The resulting solid was filtered, washed with water and dried in a vacuum oven to give N-cyclopropyl-2-(methylthio)pyrazolo[1,5-a][1,3,5]triazin-4-amine as a tan solid (5.44 g, 79% yield). LCMS (ES): >95% pure, m/z 222 [M+H]+.
