Synthetic Route of 3177-24-0, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 3177-24-0, name is 2,4-Dichloropyrimidine-5-carbonitrile. A new synthetic method of this compound is introduced below.
Example 287: Preparation of 4-(cyclopropylamino)-2-((2-oxo-l,2,3,4-tetrahydroquinolin-6- yl)amino)pyrimidine-5-carbonitrile and 2-(cyclopropylamino)-4-((2-oxo-l,2,3>4- tetrahydroquinolin-6-yl)amino)pyrimidine-5-carbonitrile.2,4-Dichloropyrimidine-5-carbonitrile (0.100 g, 0.575 mmol), cyclopropanamine (0.040 ml, 0.575 mmol) and N-ethyl-N-isopropylpropan-2-amine (0.1 10 ml, 0.632 mmol) were mixed in acetonitrile (2 ml). The mixture was microwaved at 70 °C for 10 min and then concentrated. 6- amino-3,4-dihydroquinolin-2(l H)-one (0.093 g, 0.575 mmol) and acetic acid (0.035 g, 0.575 mmol) were added. The mixture was microwaved at 1 10 °C for 20 min and then concentrated. 14 mg of 4-(cyclopropylamino)-2-((2-oxo- l ,2,3,4-tetrahydroquinolin-6-yl)amino)pyrimidine-5- carbonitrile and 14 mg of 2-(cyclopropylamino)-4-((2-oxo-l ,2,3,4-tetrahydroquinolin-6- yl)amino)pyrimidine-5-carbonitrile were recovered after automated reverse phasechromatography (water-MeCN). MS calcd for [Ci7Hi6N60+H]+: 321.15 found 321.00.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,3177-24-0, its application will become more common.
