5-Fluorouracil derivatives. III. A simple method to prepare 5-fluoro-2'-deoxyuridine derivatives.
3',5'-Diacyl-2'-bromo-5-fluoro-2'-deoxyuridine (4) was obtained by the reaction of 5, 6-dihydro-6-hydroxy-5-fluorouridine (2) and acyl bromide. Because the route from uridine (1) to 2, the route from 4 to 3',5'-diacyl-5-fluoro-2'-deoxyuridine (5), and the route from 5 to 5-fluoro-2'-deoxyuridine (FUDR, 6) are known reactions, the three step synthesis from uridine to 5 and four step synthesis from uridine to FUDR have been accomplished.
