制备方法与用途

简介

2-氯-4-氰基嘧啶是一种嘧啶环衍生物。嘧啶环是药物、天然产物中最常见的杂环之一。作为合成抗癌和抗艾滋病药物等的中间体，嘧啶类杂环化合物在医药领域具有重要应用价值。

应用

2-氯-4-氰基嘧啶可用于制备2-氯嘧啶-4-甲酸，后者是治疗高磷血症的关键，并且作为合成苯磺酰胺吡唑激酶抑制剂的重要中间体，在国内外广泛应用于医药中间体的合成。该化合物展现出良好的市场前景。

制备

将100克2-羟基-4-甲基嘧啶分散于275毫升6摩尔/升稀盐酸中，混合后置于反应器中，并降温冷却至0-5℃。随后，在此温度下缓慢滴加含有63克亚硝酸钠的50毫升水溶液，待完全滴加完毕后，在相同条件下保温反应2-5小时。过滤并干燥得到110克中间体，直接用于下一步反应。

将100克中间体悬浮于500毫升三氯氧磷中，并滴加50毫升三乙胺。这一步骤会产生大量白烟并明显升温。待三乙胺完全滴加完毕后，加热至100℃保温反应3-4小时。冷却后减压浓缩去除多余的三氯氧磷，将残余物缓慢倒入1千克碎冰中搅拌约1小时。使用200毫升乙酸乙酯萃取，并用饱和碳酸氢钠水溶液洗至pH值中性，再用水洗一次。最后，使用无水硫酸钠干燥并浓缩后重结晶，最终获得66.7克纯度大于98%的2-氯-4-氰基嘧啶，收率为66%。
