制备方法
生产方法以5-甲氧基嘧啶为原料合成5-羟基嘧啶的一般步骤:将5-甲氧基嘧啶(2.99g,27.2mmol)与粉末状氢氧化钾(8.96g,85%,136mmol)在甲醇(50mL)中的混合物置于密封管中,于150℃下加热反应过夜。反应完成后,将混合物冷却至室温,加入乙酸进行中和,随后在减压条件下浓缩。所得残余物用热乙腈(2×100mL)研磨,合并乙腈萃取液并减压浓缩,得到7.51g灰白色固体。将该固体用热乙酸乙酯(100mL)研磨,减压浓缩乙酸乙酯萃取液,得到1.81g灰白色固体。最后,通过快速色谱法(硅胶为固定相,9:1的二氯甲烷/甲醇为流动相)进一步纯化,得到目标产物5-羟基嘧啶(1.11g,收率43%),为灰白色固体。其1H NMR(300MHz,DMSO-d6)数据如下:δ10.45(宽单峰,1H),8.67(单峰,1H),8.34(单峰,2H)。参考文献:[1] Chemistry - A European Journal, 2003, vol. 9, # 20, p. 4997 - 5010[2] Patent: US2006/173049, 2006, A1.
