Embodiment 1
[0020] Example 1: Compound ZDBB-1 preparation of
[0021] The synthetic route is as follows:
[0022]
[0023] The synthetic route of intermediate 1 can be found in reference (Varache-Lembege, et al, European Journal of Medicinal Chemistry, 2008, 43, 1336-1343.).
[0024]
[0025] The synthetic route of compound ZDBB-1 can be found in the reference (Shoujiao Peng et al, J.Med.Chem.2015,58, 5242-5255).
[0026] Add raw material 110mmol, intermediate 210mmol, CH 2 Cl 2 10ml, 10ml of triethylamine, stirred at room temperature for 10h. Then add saturated NH 4 Washed with Cl solution, CH 2 Cl 2 Extraction, washing with saturated brine, MgSO 4 Dried and concentrated. The crude product was separated by column chromatography with a yield of 75%.
