Process for the preparation of 2-fluoro-9-(2,3,5-tri-O-benzyl-beta-arabinofuranozyl)adenine. |
摘要 |
<p>A process for the preparation of 2-fluoro-9-(2,3,5-tri-O-benzyl-beta-D-arabinofuranosyl)adenine (I) is described. The process involves reacting a protected 2-fluoro adenine with a protected chlorosugar under controlled conditions of temperature (80-85 DEG C) to produce (I), rather than using a process involving fluorinating a 2-substituted nucleoside precursor of (I).</p> |
