| titleOfInvention | Process for preparing purine derivatives |
| abstract | Process for preparing the L-monovaline ester of 2-(2-amino-1,6-dihydro- 6- oxo-purin-9-yl)-methoxy-1,3-propanediol of the formula I, (See formula I) and its pharmaceutically acceptable salts. The present process provides an N ,O- bis- trityl intermediate of 2-(2-amino-1,6-dihydro-6-oxo-purin-9-yl)-methoxy-1,3- propanediol which allows for monoesterification by an L-valine derivative. These products are of value as antiviral agents with improved absorption. |
