Verwenden
7-Methylxanthine can be used as a building block to synthesize tricyclic imidazo[2,1-i]purinone derivatives as potential adenosine receptor antagonists.
Definition
ChEBI: An oxopurine that is xanthine in which the hydrogen attached to the nitrogen at position 7 is replaced by a methyl group. It is an intermediate metabolite in the synthesis of caffeine.
Allgemeine Beschreibung
7-Methylxanthine is an oxopurine, which belongs to the class of xanthines. It may be synthesized by the reaction between 4-amino-1-methylimidazole-5-carboxamide and diethyl carbonate.
l?uterung methode
Crystallise it from water. [Beilstein 26 II 263, 26 III/IV 2330.]
