Procedure

The title compound was prepared in analogy to Example 2, by using [(2R,3R,5S)-5-[acetoxy(cyclopropyl)methyl]-2-(5-amino-2-oxo-thiazolo[4,5-d]pyrimidin-3-yl)tetrahydrofuran-3-yl] acetate (compound 16a) instead of [(2R,3R,5S)-5-(1-acetoxypropyl)-2-(5-amino-2-oxo-thiazolo[4,5-d]pyrimidin-3-yl)tetrahydrofuran-3-yl]acetate (compound 2a). Example 17 was purified and separated by preparative HPLC to afford Example 17-A and Example 17-B as white solid.
