Pyridine → HCID 88632727, compound

Participants

Reaction Steps

Into 50 ml of pyridine were dissolved 3.16 g of 5'-benzoyl-2',3'-dideoxy-uridine and 0.22 g of distilled water. Then, after added 2.67 g of phosphorus pentasulfide at room temperature under stirring, the mixture was refluxed for 3 hours. After the completion of reaction, the solids deposited by allowing to cool were collected by filtration, which were washed with small amount of pyridine. The pyridine filtrate obtained was concentrated to dryness and the residue was extracted with chloroform to separate 3.15 g of 5'-benzoyl-2',3'-dideoxy-4-thio-uridine(yield: 95%).
