Embodiment 1

[0050] Preparation of 1-(5′-deoxy-β-D-ribofuranose)-3-(3′-p-fluorobenzyl-1′,2′,3′-triazolyl)-methylene-5-fluorouracil (compound Ⅰ-1 ）

[0051] Add 1-(5′-deoxy-β-D-ribofuranose)-5-fluorouracil (8.1mmol, 2g), DMF (20ml), K 2 CO 3 (28.9mmol, 4g), propyne bromide (24.3mmol, 1.9ml), stirred at room temperature, and reacted for 3-5 hours until TLC (254nm, petroleum ether: acetone = 1:1) detected that the raw materials were consumed. After the reaction is completed, add 15ml of distilled water, extract with ethyl acetate (15ml×2), combine the ethyl ester phases, dry with 4g of magnesium sulfate for 3 hours, and vacuum-filter and then rotary evaporate for 40 to obtain a yellow solid, weigh 2.2g after vacuum drying, and set aside. Yield 95.7%.

[0052] Add the above-prepared compound (0.7mmol, 200mg), the mixed solution of tert-butanol and water (9ml, tert-butanol / water=8 / 1), Cu (2.8mmol, 179mg) and CuSO 4 (0.7mmol, 124mg), p-fluorobenzyl azide (2.1mmol, 317mg), react at 50°C fo...

Embodiment 2

[0054] Compounds I-2 to I-15 were synthesized with reference to Example 1, and the corresponding aromatic methyl azides were used in step (2).

Embodiment 3

[0056] Synthesis of compound II-1

[0057] Take the compound 1-(2',3'-O-isopropylidene-5'-p-toluenesulfonyl-β-D-ribofuranose)-5-fluorouridine (6.6g, 17mmol) in a 250mL round bottom Into the flask, add acetonitrile 100mL, potassium carbonate (24g, 17mmol), propyne bromide (4mL, 51mmol), stir at room temperature, and react for 5h, TLC (V petroleum ether: V acetone = 3:1) detects that the reaction of raw materials is complete, stop reaction. Diatomaceous earth filter aid, ethyl acetate washed the filter cake, combined organic phase, rotary steamed, added ethyl acetate 80mL, washed with distilled water three times, added magnesium sulfate to dry, suction filtered and rotary steamed to obtain a white solid, weighing 6.3g, Yield 82%, standby.

[0058] Take the compound obtained above (0.297g, 0.66mmol) and place it in a 25mL round bottom flask, add 8mL of tert-butanol and 1mL of water as a mixed solvent, add copper powder (0.128g, 2.0mmol) and copper sulfate (0.083g, 0.33mmol) ...
