制备方法与用途

化学性质
这种物质为白色鳞片状结晶，熔点在203-204℃之间。它易溶于水和碱性溶液，并可溶解于乙酸及热乙醇中，但在乙醇、丙酮、氯仿和乙醚中不溶。

用途
该化合物是一种抗肿瘤药物。

生产方法
由氟乙酸乙酯经缩合反应制备。首先将甲醇钠加入干燥的反应锅内，随后用甲酸乙酯除去甲醇钠中的游离碱，并在搅拌下进行常压蒸馏以去除甲醇，直至甲醇钠变成白色粉末。降温至50℃后，加入甲苯，再降至10℃以下滴加甲酸乙酯。完成后，在20-25℃条件下继续反应7小时，然后降至10℃以下，加入无水甲醇和乙酸甲脒，并搅拌直至反应物固化，静置过夜。随后添加盐酸并加热以使固化物溶解，过滤后滤液进行常压蒸馏去除部分液体，冷却结晶，过滤获得粗品。最后，使用无水乙醇重结晶，并通过活性炭脱色即得5-氟-4-羟基嘧啶。
