Procedure

A mixture of 5 g of 7-β-D-arabinofuranosyl-3,7-dihydro-4H-pyrrolo[2,3-d]pyrimidine-4-thione, 5 g of Raney nickel, and 250 ml of water is stirred and heated under reflux for one hour and filtered while hot. The filtrate is evaporated in vacuo to a small volume and cooled to provide pure 7-β-D-arabinofuranosyl-7H-pyrrolo[2,3-d]pyrimidine.
