<p>An improved method for synthesizing 1-(tetrahydro - 2-furanyl) - 5-fluorouracil from a silyl derivitive of 5-fluorouracil (bis - trimethylsilyl 5-fluorouracil) by reacting the same with 2-chlorotetrahydrofuran. The reaction is carried out at controlled conditions of temperature and under an inert gas. Yields in excess of 80% of the theoretical are obtained as calculated upon the starting amounts of 5-fluorouracil.</p> |
