The condensation of 4-hydroxy-6-methyl-2(1H)-pyridones 1 with araliphatic amino compounds 2 gives rise to the 4-alkylamino-6-methyl-2(1H)-pyridones 3. Irradiation using an ordinary domestic microwave oven provides a fast and simple method for their preparation. However, under the conditions used, aliphatic and aromatic amines gave no reaction
将
4-羟基-6-甲基-2(1H)-
吡啶酮 1 与芳香族
氨基化合物 2 缩合,可得到 4-烷基
氨基-6-甲基-2(1H)-
吡啶酮 3。使用普通家用微波炉进行辐照是制备这些化合物的一种快速而简单的方法。然而,在所使用的条件下,脂肪族和芳香族胺没有发生反应
