1-Alkyl-8-bromo-3-methyl-7-(1,1-dioxo-1 lambda(6)-thietan-3-yl)-3,7-dihydro-1H-purine-2,6-diones reacted with amines to give the corresponding 1-alkyl-8-amino-3-methyl-7-(1,1-dioxo-1 lambda(6)-thietan-3-yl)-3,7-dihydro-1H-purine-2,6-diones which were treated with sodium alkoxide to remove thietanyl protecting group with formation of 1-alkyl-8-amino-3-methyl-3,7-dihydro-1H-purine-2,6-diones possessing no substituent on N-7.
