Procedure
A solution of 5.0 g of 1-(2,3,5-tri-O-acetyl-β-D-arabinofuranosyl)-1,5-dihydro-4H-imidazo[4,5-c]pyridine-4-thione, 200 ml of methanol, and 54 mg of sodium metholate is heated under reflux for 2 hours and treated with IRC-50 ion exchange resin. The filtrate is evaporated in vacuo and the resulting residue is recrystallized from ethanol-water to provide 1-β-D-arabinofuranosyl-1,5-dihydro-4H-imidazo[4,5-c]pyridine-4-thione.
