5-氟胞嘧啶制备

1.由5-氟尿嘧啶经氯化、氨化、水解而得。1.氯化将5-氟尿嘧啶和三氯氧磷加入氯化锅，搅拌，控制在20℃以下滴加N,N-二甲基苯胺。滴加完毕，升温到110℃左右反应2h。冷至室温，放至冰盐水中冰解，维持15℃搅拌1h。过滤，水洗，得2,4-二氯-5-氟嘧啶。2.氨化将2,4-二氯-5-氟嘧啶溶解在乙醇中，搅拌，控制在35℃以下滴加氨水。滴毕，降温至25℃反应3h，减压回收乙醇至干，加水搅拌升温到20℃。过滤，用水洗涤结晶，干燥，得出4-氨基-2-氯-5-氟嘧啶。3.水解将4-氨基-2-氯-5-氟嘧啶和盐酸混合，搅拌升温至90-95℃,反应2h后，减压浓缩至干，加水溶解结晶，加活性炭脱色。过滤，滤液用氨水调pH至7-8，放置过夜。甩滤，用水洗涤结晶，经精制即得氟胞密啶。总收率50%。该法的起始原料为抗癌药氟尿嘧啶[51-21-8]，也可以采用氟尿嘧啶的前体，即2-甲氧基-4-羟基-5-氟嘧啶为原料，经氯化，氨化，水解制备氟胞嘧啶，收率70%。将上述前体加入甲苯中，再加入二甲基苯胺，加热至50-60℃，滴加三氯氧磷。然后105-110℃反应3h。冷却至室温，将反应液加入甲苯和水的混合液中，在25-40℃搅拌。分出甲苯层，水层用甲苯提出取，将提出取液与甲苯层合并，先减压回收甲苯，再收集86-90℃（2.66kPa）馏分即得2-甲氧基-4-氯-5-氟嘧啶。将上步氯化产物与无水甲醇加入压力釜中，在室温下通氨至饱和，缓缓升温使压力达到0.5MPa，搅拌反应过夜。冷到室温出料，经处理得2-甲氧基-4-氨基-5-氟嘧啶，熔点189-191℃。将其与30%盐酸在100-105℃反应3h。水解物减压蒸干，用水溶解残留物，加氨水碱化到pH8.5，冷却至5℃以下，过滤，得氟胞嘧啶粗品，用水重结晶即得成品。
