N-(2-Amino-4,6-dichloro-5-pyrimidinyl)formamide Chemical Properties,Usage,Production

Chemical Properties

White crystalline powder

Uses

N-(2-Amino-4,6-dichloro-5-pyrimidinyl)formamide (Abacavir - In House Impurity) is an intermediate of Abacavir (A105000). Abacavir is a carbocyclic 2''-deoxyguanosine nucleoside reverse transcriptase inhibitor and an anti-HIV drug used to treat HIV infection (1). Intracellular enzymes convert Abacavir to its active form, carbovir-triphosphate (CBV-TP), which then selectively inhibits HIV reverse transcriptase by incorporating into viral DNA (2). Abacavir is metabolized in the liver by uridine diphosphate glucuronyltransferase and alcohol dehydrogenase resulting in inactive glucuronide and carboxylate metabolites, respectively.

Uses

Prasugrel intermediate

Uses

Abacavir intermediate. A purine derivative

171887-03-9

1. 2,5-diamino-4,6-dichloropyrimidine (0.01 mol, 2.0 g) was mixed with water (0.25 mol, 4.55 mL) at room temperature and stirred. 2. 98% formic acid (0.4 mol, 18.27 g, 14.97 mL) was slowly added to the reaction system. 3. The reaction mixture was heated to 50-55 °C and maintained at this temperature for 3 hours. 4. Upon completion of the reaction, toluene (0.38 mol, 34.6 g, 40 mL) was added to the reaction system at 50 °C for azeotropic distillation. This process was repeated once, using a total of 80 mL of toluene to ensure adequate distillation. 5. After the reaction mixture was cooled, the solid product was collected by filtration and washed with cold water. 6. The washed product was dried under vacuum at 60°C. 7. 7. 2-amino-4,6-dichloro-5-formamidopyrimidine (0.01 mol, 2.0 g) was finally obtained in about 90% yield.
