Embodiment 1
[0025] 1) Synthesis of 5'-trityl fluorouridine:
[0026] In a three-necked flask equipped with a thermometer, add 0.98g (0.004mol) of floxuridine and 20ml of pyridine, stir to dissolve them, then add 1.56g (0.0056mol) of triphenylmethyl chloride and a catalytic amount of 4-bis Aminopyridine. The reaction mixture was in N 2 Stir the reaction at room temperature under protection for 12 hours, heat to 100°C for 3 hours, cool to room temperature, pour into about 100ml of ice water, and extract 3 times with ethyl acetate (40ml×3), the obtained organic phase is sequentially washed with 2mol / L hydrochloric acid , water, saturated NaHCO 3 solution, washed with saturated NaCl solution, and the resulting organic phase was dried over anhydrous sodium sulfate. After filtration and recovery of the organic solvent, the resulting residue was separated by silica gel column chromatography [chloroform:methanol (V / V)=20:1] to obtain 0.85 g of a white solid which was 5′-tritylfluridine. The m...
Embodiment 2
[0032] 1) Synthesis of 5'-trityl fluorouridine:
[0033] In a three-necked flask equipped with a thermometer, add 1.34g (0.0054mol) of floxuridine and 25ml of triethylamine, stir to dissolve them, then add 3.45g (0.012mol) of triphenylmethyl chloride and a catalytic amount of 4 - Dimethylaminopyridine. The reaction mixture was in N 2 Stir the reaction at room temperature under protection for 12 hours, heat to 70°C for 3 hours, cool to room temperature, pour into about 100ml of ice water, and extract 3 times with chloroform (40ml×3), the obtained organic phase is sequentially washed with 2mol / L hydrochloric acid, water , saturated NaHCO 3 solution, washed with saturated NaCl solution, and the resulting organic phase was dried over anhydrous sodium sulfate. After filtration and recovery of the organic solvent, the obtained residue was separated by silica gel column chromatography [chloroform:methanol (V / V)=20:1] to obtain 1.08 g of white solid which was 5′-tritylfluridine. T...
Embodiment 3
[0039] 1) Synthesis of 5'-trityl fluorouridine:
[0040] In a three-necked flask equipped with a thermometer, add 1.12g (0.0046mol) of floxuridine, 15ml of triethylamine, and 12ml of diisopropylethylamine, stir to dissolve them, and then add 4.36g (0.0157mol) of triphenyl methyl chloride and a catalytic amount of 4-dimethylaminopyridine. The reaction mixture was in N 2 Stirring reaction at room temperature under protection for 12h, heating to 80°C for 3h, cooling to room temperature, pouring into 100ml of ice water, and extracting 3 times with 1,-dichloroethane (40ml×3), the obtained organic phase was successively washed with 2mol / L hydrochloric acid, water, saturated NaHCO 3 solution, washed with saturated NaCl solution, and the resulting organic phase was dried over anhydrous sodium sulfate. After filtration and recovery of the organic solvent, the resulting residue was separated by silica gel column chromatography [chloroform:methanol (V / V)=20:1] to obtain 1.20 g of a w...
