| titleOfInvention | Preparation of 5-fluorouracil |
| abstract | PURPOSE: To prepare 5-fluorouracil useful as a carcinostatic agent, in a simple process, by the deamination of 5-fluoro-6-hydroxy-5,6-dihydrocytosine at proper temperature and acid concentration, followed by the dehydration at an elevated temperature. n CONSTITUTION: 5-Fluorouracil of formula II is prepared by (1) deaminating 5-fluoro-6-hydroxy-5,6-dihydrocytosine of formula I in an aqueous solution containing 0.1W6 M/l of an acid (e.g. HC1) at 20W70°C, and (2) dehydrating the product by heating at 70W100°C, pref. 90W100°C. n COPYRIGHT: (C)1979,JPO&Japio |
