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. 3029-64-9, name is 2,4,6-Trichloro-5-cyanopyrimidine. A new synthetic method of this compound is introduced below., Computed Properties of C5Cl3N3
EXAMPLE VIII 4,6-Dichloro-2-diethylamino-5-pyrimidinecarbonitrile A stirred solution of 6.3 grams of 2,4,6-trichloro-5-pyrimidinecarbonitrile in 150 ml of diethyl ether was cooled to -10°, and a solution of 4.4 grams of diethylamine in 75 ml of diethyl ether was added dropwise. Upon complete addition, the reaction mixture was stirred at -10° for 1 hour. Water was added to the reaction mixture. The diethyl ether layer was separated and dried over magnesium sulfate. The mixture was filtered, and the filtrate was evaporated under reduced pressure to a residue. The residue was recrystallized from methylcyclohexane to give 3.8 grams of 4,6-dichloro-2-diethylamino-5-pyrimidinecarbonitrile; mp, 125°-126°. Analysis: Calculated for C9 H10 Cl2 N4: C,44.10; H,4.07; N,22.85; Found: C,44.l3; H,4.28; N,23.14.
