    摘要: Described is a new process for producing temozolomide, comprising the reaction between 5-aminoimidazole-4-carboxamide and N-succinimidyl-N′-methyl carbamate and the subsequent reaction of the thus obtained carbamoyl 5-aminoimidazole-4-carboxamide with sodium nitrite. Temozolomide is then purified by chromatography on adsorbent polymeric resin and subsequent crystallization from water and acetone.
