3-dimethyluracils, although a steric effect of the methyl group at 6-position complicated the reaction. On the other hand, a similar treatment of 1,3-dimethylthymine led to alkylation of the methyl group at 5-position. The reaction of caffeine gave 8-alkylcaffeines and alkyl acetates were used as favorable solvents with respect to synthesis of 8-alkylcaffeines.
