Synthesis and Application of 2-Aamino-6-chloropurine

This paper reviewed the synthetic methods and applications in the pharmaceutical field of 2 amino 6 chloropurine basing on many recent document.2 Amino 6 chloropurine is an important pharmaceutical intermediate for production of the compound useful as an antiviral, anticancer, anti inflammatory and hypotensor drugs. The synthetic methods of 2 amino 6 chloropurine comprises guanine reacting by chlorine sparging, guanine reacting directly with chlorinating agent, guanine protecting by acyl group and then reacting with chlorinating agent, derivative of pyrimidine reacting with chlorinating agent thereafter ring closing etc. The last two methods were sensible for there simple industrial art, moderate operating condition and high yield.
