successfully used for the production of nitro derivatives of 2and 4-pyridones [i, 2]. Actually, in the case of nitration of 2-methoxymethyl-4-methyl-5-cyano-6-pyridone (I) and 2,4-dimethyl-5-cyano-6-pyridone (II) with a mixture of HN03 and H=SO~, we isolated 2-methoxymethyl-3-nitro-4-methyl-5-cyano-6-pyridone (III) and 2,4-dimethyl-3-nitro-5-cyano-6-pyridone (IV) with yields of 56 and 65%, respectively
硝酸和硫酸的混合物成功地用于生产 2 和 4-吡啶酮的硝基衍生物 [i, 2]。实际上,在用 HNO3 和 H 的混合物硝化 2-甲氧基甲基-4-甲基-5-氰基-6-吡啶酮 (I) 和 2,4-二甲基-5-氰基-6-吡啶酮 (II) 的情况下=SO~,我们分离了 2-甲氧基甲基-3-硝基-4-甲基-5-氰基-6-吡啶酮 (III) 和 2,4-二甲基-3-硝基-5-氰基-6-吡啶酮 (IV)产率分别为 56% 和 65%。
