Embodiment 1
[0032] A preparation method of genistein derivatives, comprising the steps of:
[0033] (1) Synthesis of 5-fluorouracil-1-acetic acid: at first, add 1.6g 5-fluorouracil and 30ml of alkaline aqueous solution of 10wt% in the three-necked flask that is equipped with reflux condenser and magnetic force stirring, then slowly add to the three-necked flask Add 4ml of 0.525g / mL chloroacetic acid solution dropwise. After the dropwise addition, heat and stir in a water bath at 60°C for 5 hours. After the reaction, cool the reaction solution to room temperature, adjust the pH value to 2, and then place it in a refrigerator at 4°C to cool overnight. , suction filtration, and drying to obtain needle-like crystal 5-fluorouracil-1-acetic acid, the specific reaction formula is as follows:
[0034]
[0035] (2) Preparation of genistein derivatives: take 0.5 g of 5-fluorouracil-1-acetic acid prepared in the above step (1) in a three-necked flask, then add 0.6 g of genistein, 0.6 g of catalys...
Embodiment 2
[0038] A preparation method of genistein derivatives, comprising the steps of:
[0039] (1) Synthesis of 5-fluorouracil-1-acetic acid: at first, add 1.6g 5-fluorouracil and 40ml of alkaline aqueous solution of 10wt% in the three-necked flask that is equipped with reflux condenser and magnetic force stirring, then slowly add to the three-necked flask Add 4ml of 0.65g / mL chloroacetic acid solution dropwise.
