The downstream synthesis method of this compound is introduced below.

To a stirred solution of THF (5 mL) containing compound 3 (350 mg, 1.03 mmol) were added sequentially, HOBT (224 mg,1.6 mmol), EDC.HCl (306 mg, 1.6 mmol), TEA (0.28 mL, 2.0 mmol) and methyl 5-amino-2-methylbenzoate (3a) (198 mg, 1.2 mmol). The resulting mixture was stirred at room temperature for 12 h. The reaction mixture was diluted with dichloromethane (10 mL) followed by water (15 mL), the organic layer was separated, washed with water (2 ¡Á 15 mL) followed by brine solution to obtain the crude compound 4. The crude compound was purified by column chromatography using 60-120 silica gel and eluted with 30 % EtOAc/hexane to afford compound 4.
