Embodiment 1
[0046] 1) Synthesis of Compound 1
[0047] a) Synthesis of Compound 16
[0048]Add 8.00 g of 3-hydroxymethylpiperazine carbonate tert-butyl carbonate (37.0 mmol) to a solution containing 80 mL of 1,4-dioxane, 80 mL of water and 11.8 g of sodium carbonate (111 mmol) at 0 °C The mixed solution was then added with 4.90 g of allyl chloroformate (40.7 mmol), and then warmed to room temperature and stirred for 16 hours. Add 70 ml of water to the reaction solution, and extract with ethyl acetate (200 ml×3). The organic phases were combined, dried over anhydrous sodium sulfate, spin-dried, and purified on a silica gel column (petroleum ether: ethyl acetate (volume ratio) = 20:1 to 3:1) to obtain 10.0 g of white oil 16 (yield: 90.0%) . 1 H NMR (400 MHz, CDCl 3 ) δ 5.97-5.90 (m, 1H), 5.32-5.20 (m, 2H), 4.60 (d, J = 5.2 Hz, 2H), 4.31-4.13 (m, 2H),4.02-3.84 (m, 2H), 3.63 (br.s., 2H),3.12-2.85 (m, 3H), 2.85-2.64 (m, 1H), 1.46 (s, 9H).
[0049] b) Synthesis of Compound 17

Embodiment 2
[0068]
[0069] 2) Synthesis of Compound 2
[0070] Dissolve 35.0 mg of compound 25 (75.3 μmol) and 31 μl of triethylamine (0.23 mmol) in 4 ml of dichloromethane, add 7.0 μl of cyclopropylformyl chloride (77 μmol) at 0 °C, The reaction was stirred at 20°C for 1 hour. Add 20 ml of water and extract with dichloromethane (50 ml x 2). The organic phase was dried over anhydrous sodium sulfate and spin-dried. The obtained crude product was purified by preparative high performance liquid chromatography to obtain 6.9 mg of compound 2 as a white solid (yield: 21.5%). ESI-MS m / z : 497.1 [M+H] + .
Embodiment 3
[0072]
[0073] 3) Synthesis of compound 3
[0074] Dissolve 30.0 mg of compound 25 (64.5 μmol) and 27 μl of triethylamine (0.19 mmol) in 4 ml of dichloromethane, and add 7.1 μl of 2-methoxyacetyl chloride (77 μmol ), and the reaction was stirred at 20 °C for 1 h. Add 20 ml of water and extract with dichloromethane (50 ml x 2). The organic phase was dried over anhydrous sodium sulfate and spin-dried. The obtained crude product was purified by preparative high performance liquid chromatography to obtain 14.5 mg of white solid compound 3 (yield: 44.9%). ESI-MS m / z : 501.1 [M+H] + .
