| titleOfInvention | A PROCESS FOR THE PREPARATION OF A COMPOUND IMIDAZO-TETRAZIN-4-ONA AND A PROCESS FOR THE PREPARATION OF TEMOZOLOMIDE AND INTERMEDIARIES |
| abstract | A process for the preparation of an imidazo-tetrazin-4-one compound of the formula (1) in which R is a C1-6 alkyl group, which comprises the reaction of a compound of the formula (2) in which R it is as defined above, with an oxidation / cyclization agent in the presence of an iodide, in an inert medium, under an inert atmosphere and at a temperature and for a period sufficient to produce a compound of the formula (1), where said iodide It is soluble in said inert medium, and a process for the preparation of temozolomide and intermediates. Anti-tumor |
