  • Method of synthesizing 1-(tetrahydro-2-furanyl)-5-fluorouracil
    Patent number: 3960864
    Abstract: 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.
