Abacavir intermediate and method for purifying same

The invention discloses an abacavir intermediate and a method for purifying the same. The method includes heating mixtures with abacavir intermediate crude products, purified water and water-soluble organic solvents until the abacavir intermediate crude products are completely dissolved so as to obtain mixed liquid; carrying out cooling and crystallization treatment on the mixed liquid; carrying out filtering and drying treatment after crystallization treatment is carried out so as to obtain abacavir intermediate pure products. A structural formula of the abacavir intermediate is shown as a formula IV. The abacavir intermediate and the method have the advantage that the method is easy and convenient to implement and is suitable for industrial production.

Process for the synthesis of chloropurine intermediates

The present invention relates to a process for the preparation of a carbocyclic purine nucleoside analogue of formula (I), its salts and pharmaceutically acceptable derivatives thereof which comprises hydrolysing a compound of formula (IV) wherein P is a protecting group, in the presence of an acid, condensing the product of formula (V) formed in situ in the presence of a base with a compound of formula (VI) followed by in situ ring closure of the resulting intermediate.

An efficient, scalable synthesis of the HIV reverse transcriptase inhibitor Ziagen (1592U89)

Ziagen, (1S, cis)-4-[2-amino-6-(cyclopropylamino)-9H-purin-9-yl]-2- cyclopentene-1-methanol, was synthesized from (1S,4R)-azabicyclo[2.2.1]hept- 5-en-3-one by efficient processes which bypass problematic steps in earlier routes. 2-Amino-4,6-dichloro-5-formamidopyrimidine is a key intermediate which makes possible an efficient construction of the purine from a chiral cyclopentenyl precursor.
