Reaction of 1,3-dimethyllumazine with N-bromosuccinimide or bromine in an appropriate alcohol afforded 6-alkoxy-1,3-dimethyllumazine. N-Iodosuccinimide or iodine also brought about the same reaction. This procedure was applicable to other pteridine compounds, such as 2-dimethylamino-4(3H)-oxopteridine. The mechanism of this alkoxylation reaction is discussed.
