The Synthetic Routes of Nelarabine

Nelarabine is a synthetic compound that is widely used in the pharmaceutical industry for the treatment of cancer.
It is a nucleoside analogue that is specifically used for the treatment of T-cell lymphoma, a type of blood cancer that affects the immune system.
The synthetic route of nelarabine is a complex and multistep process that involves the synthesis of several intermediate compounds.
In this article, we will discuss the synthetic routes of nelarabine in detail.

Step 1: The synthesis of 2,6-diaminopurine
