Embodiment 1

[0057] The preparation of embodiment 1 compound I-1

[0058]

[0059] Compound I-a1 (267mg, 1.1mmol), Compound I-b1 (162mg, 1.0mmol), (2-(7-aza-1H-benzotriazol-1-yl)-1,1,3, 3-Tetramethyluronium hexafluorophosphate (HATU) (456mg, 1.2mmol) and N-methylmorpholine (13μL, 1.2mmol) were added to DMF, kept at 70°C and stirred for 8 hours. Concentrated under reduced pressure to remove the solvent, the The residue was suspended in acetonitrile and the solid product was isolated by filtration, washed with water (80 mL), acetonitrile (80 mL), acetone (80 mL) and dried under vacuum to afford 212 mg of off-white solid (54.9% yield), That is the product compound I-1. (LC / MS: [M+H] + 387).

Embodiment 2

[0060] The preparation of embodiment 2 compound 1-2

[0061] The preparation method of compound 1-2 was experimented in a manner similar to that of Example 1, but the starting material compounds used were different. After the reaction was completed, the products were separated to obtain compound I-2 respectively, and the products were verified by LC / MS. Compound I-2 (LC / MS: [M+H] + 401).

Embodiment 3

[0062] The preparation of embodiment 3 compound 1-3

[0063] The preparation method of compound 1-3 was experimented in a manner similar to that of Example 1, but the starting material compounds used were different. After the reaction, the products were separated to obtain compound I-3 respectively, and the products were verified by LC / MS. Compound I-3 (LC / MS: [M+H] + 429).
