icotinic acid hydrazide as starting material. Treatment of the hydrazide with carbon disulfide to afford the oxadiazole derivative, which was treated with 5-methyl-2-furancarbaldehyde, formic acid, acetic acid/acetic anhydride, or phthalic anhydride to yield the corresponding pyridinodiazoles and on imide. Condensation of the hydrazide with p -fluorobenzaldehyde in ethanol or acetic acid in the presence
以2-氯-6-肼基异烟碱酸酰肼为起始原料,合成了一系列恶二唑吡啶衍生物。用二硫化碳处理酰肼,得到恶二唑衍生物,将其用5-甲基-2-呋喃甲醛,甲酸,乙酸/乙酸酐或邻苯二甲酸酐处理,得到相应的吡啶二唑和酰亚胺。在乙酸钠存在下,将酰肼与 对 氟苯甲醛在乙醇或乙酸中缩合,得到和恶二唑衍生物,将其乙酰化并用乙酸酐环化成 N -乙酰氧基二唑衍生物。acetate在乙酸钠或溴水/乙酸钠的存在下用乙酸处理,得到恶二唑,而TE在 TEA 的存在下用氯乙酰氯环化成氧杂ze丁二氨基异烟酰胺 。最后,在回流的冰醋酸中酰肼与酸酐的缩合得到相应的双酰亚胺衍生物。的药理筛选表明,许多这些得到的化合物的具有良好活性antianexiety媲美地西泮®作为阳性对照。
