摘要:
4-[(4-氯-2-嘧啶基)氨基]苯腈(Ⅰ)是二芳基嘧啶类HIV-1逆转录酶抑制剂及其类似物的重要中间体.以2-硫脲嘧啶为原料,碘甲烷为甲基化试剂,氢氧化钠作碱,于室温下制备得到2-甲硫基-4-嘧啶酮(Ⅱ);经反应条件优化发现,2-硫脲嘧啶:碘甲烷:氢氧化钠的摩尔比为1.00∶1.25∶1.05时,Ⅱ的收率可达83.5%.Ⅱ无需重结晶等纯化操作即可直接与对氨基苯腈于180~190 ℃下发生无溶剂反应以71.9%的粗品收率得到4-[(4-氧-1,4-二氢-2-嘧啶基)氨基]苯腈(Ⅲ),Ⅲ不经进一步纯化直接在三氯氧磷作用以67.3%的纯品收率得到氯代产物4-[(4-氯-2-嘧啶基)氨基]苯腈(Ⅰ).三步反应累计总收率达到40.4%(以2-硫脲嘧啶计).Ⅰ经核磁共振氢谱(1H NMR)和核磁共振碳谱表征(13C NMR),产品的核磁数据与Ⅰ的结构完全吻合;除产品的特征峰和核磁溶剂峰外,未出现任何其它杂质的化学位移.I的核磁共振氢谱和核磁共振碳谱数据未曾见文献报道.
Abstract:
4-((4-chloropyrimidin-2-yl)amino)benzonitrile (Ⅰ) is an important intermediate of diarylpyrimidine HIV-1 reverse transcriptase inhibitors and its derivatives. 2-(methylthio)pyrimidin- 4(1H)-one (Ⅱ) was prepared at room temperature from 2-thiouracil using iodomethane as methylation reagent and sodium hydroxide as base. The yield of crudeⅡ reached 83.5% under the optimized molar ratio of 1.00(2-thiouracil) : 1.25(iodomethane): 1.05(sodium hydroxide).With no further purification, such as recrystallization, Ⅱreacted with para-aminobenzonitrile in the absence of solvent at 180-190℃ and the crude4-((4-oxo-1,4-dihydropyrimidin-2-yl)amino)benzonitrile (Ⅲ) was obtained with a yield of 71.9%. Then, the unpurified Ⅲreacted withphosphorus oxychloride and the chlorinated product was obtainedwith a yield of 67.3%. The three-step total yield of Ⅰreached 40.4% (calculated from 2-thiouracil). The structure of Ⅰwas confirmed byproton nuclear magnetic resonance spectra and carbon-13 nuclear magnetic resonance spectra, which showed no any other chemical shift of impurities except for the characteristic absorption peaks ofⅠ. Now the data of nuclear magnetic resonance have not been reported publicly.
