The present invention relates to 5-amino-3- (2'-O-acetyl-3'-deoxy- beta -D-ribofuranosyl) -3H-thiazolo [4,5- d] pyrimidin- P-toluenesulfonate and its use in the treatment of diseases such as viral infections, tumors and cancers. Further, it has also been found that the synthesis of 5-amino-3- (2'-O-acetyl-3'-deoxy- beta -D-ribofuranosyl) -3H-thiazolo [4,5- d] pyrimidin- (2'-O-acetyl-3'-deoxy- beta -D-ribofuranosyl) -3H-thiazolo [4,5- d] Pyrimidin-2-one, which are useful intermediates for the preparation of pharmaceutical compositions such as p-toluenesulfonate, and the like. |
