実験手順

1-(3-O-Acetyl-5-O-benzoyl-2-deoxy-2-fluoro-β-D-arabinofuranosyl)-5-bromocytosine (1.0 g) is dissolved in saturated methanolic ammonia (100 ml) and the solution is left standing for 24 hours at room temperature. The solvent is removed in vacuo and the residue was crystallized from ethanol to give 560 mg of 1-(2-deoxy-2-fluoro-β-D-arabinofuranosyl)-5-bromocytosine, m.p. 201°-202°.
