treatment with sodium thiobenzylate and diazotization. Condensation of the silyl derivative of 8 with a protected 2-deoxyribofuranosyl chloride gave α and β anomers of 5-benzylthiopyrazine nucleosides. Reaction of 2,5-dichloropyrazine 4-oxide with sodium thiobenzylate followed by hydrolysis gave 5-benzylthio-1,2-dihydro-2-oxopyrazine 4-oxide (16).
