HCID 1354296822-Amino-7-((2R,3R,4R,5R)-3,4-dihydroxy-5-(hydroxymethyl)-3-methyltetrahydrofuran-2-yl)-3H-pyrrolo[2,3-d]pyrimidin-4(7H)-one

Procedure

A mixture of product from Step B (90 mg, 0.3 mmol) in aqueous NaOH (2N, 9 mL) was heated at reflux temperature for 5 h, then neutralized at 0° C. with 2 N aqueous HCl and evaporated to dryness. Purification on a silica gel column with CH2Cl2/MeOH, 5/1 as eluent afforded the title compound as a white solid (70 mg).
