Participants

Reaction Steps

A mixture of 2-β-D-ribofuranosylselenazole-4-carboxamide (1.0 g, 3.25 mmol), N,N-dimethylaminopyridine (catalyst, 80 mg) and acetic anhydride (15 ml) was stirred at room temperature for 3 hours. The solvent was evaporated in vacuo and coevaporated with water (10 ml×2) to provide COMPOUND 3 as a white crystalline product which was triturated with water and collected by filtration. The product was recrystallized from water containing a few drops of ethanol to provide white needles: yield 1.2 g (85 percent), mp 117-119 degrees C.
