制备方法与用途

用途

2-氯-5-氰基嘧啶是嘧啶类衍生物，可用作治疗癌症的重要医药中间体。

制备

1. 将26公斤的2-羟基嘧啶-5-羧酸甲酯和106升（29wt.%）氨水加入反应瓶中，密封后升温至32℃，反应95小时。原料完全反应后，过滤并用14升甲醇淋洗滤饼，然后在55℃烘料24小时，得到2-羟基嘧啶-5-甲酰胺9公斤。

2. 向反应瓶中加入1公斤的2-羟基嘧啶-5-甲酰胺，并缓慢加入8升三氯氧磷。将反应液升温至53℃，反应2.5小时后，再缓慢加入3公斤N,N-二异丙基乙胺（DIPEA）。在80℃下反应23小时，原料完全反应后，反应液降至室温并减压浓缩至4.5升。用5升甲基叔丁基醚提取，有机相用饱和碳酸氢钠水溶液洗涤至中性，浓缩得到产品2-氯-5-氰基嘧啶0.6公斤。按原料2-羟基-5-溴嘧啶的投入量计算，最终收率约为26.06%。
