Embodiment 1
[0333] The synthesis of embodiment 1 compound 1
[0334]
[0335] Compound 1a (25g, 0.11mol), Compound 1b (20g, 0.11mol) and K 2 CO 3 (37.5g, 0.22mol) was dissolved in DMF (200ml), and the mixture was stirred at 70°C for 3 hours. Then water (300ml) was added to the mixture, extracted with EA (200ml×3), HCl (1mol / L) was added to the aqueous phase to adjust the pH to 3-4, filtered, and the precipitate was collected and washed with methanol (5ml). After drying in air for 5 hours, 23 g of compound 1c were obtained.
[0336] Under nitrogen protection, put (COCl) in an ice bath 2 (7.2ml(COCl) 2 dissolved in 10 ml DCM) was added to a DCM solution containing compound 1c (5.0 g) and 2 drops of DMF, and stirred. After 3.5 hours the solvent was removed, the residue was dissolved in DCM and 10 ml of ethanol was added. After stirring for 1 hour, the reaction mixture was quenched with water. The organic phase was separated, dried and concentrated. The residue was purified by chro...
Embodiment 2
[0338] The synthesis of embodiment 2 compound 2
[0339]
[0340] A methanol solution of compound 1 and NaOH (0.5 ml, 2 mol / L) was stirred at room temperature for 1 hour. HCl was then added to adjust the solution to a pH of approximately 5. Filtration and drying of the solid afforded compound 2 (37 mg). MS:524.2(M+H) + .
Embodiment 3
[0341] The synthesis of embodiment 3 compound 3
[0342]
[0343] Compound 2 (140mg) and NH 2 A mixture of OH (72mg), PyBOP (180mg) was dissolved in 10ml DMF and stirred at 45°C for 3 hours. The reaction solution was purified by preparative HPLC to obtain 30 mg of solid, namely compound 3. MS:539.2(M+H) + .
