Embodiment 1
[0041] Example 1: Sodium 2-(2-(4-fluorobenzoyl)phenylamino)-3-(4-(2-(9H-carbazol-9-yl)ethoxy)phenyl)propionate preparation of
[0042]
[0043] Add 487.4g (12.18mol) of NaOH and 10.85kg of anhydrous methanol into a 50L plastic bucket, stir and dissolve at room temperature. Add 184kg tetrahydrofuran and 6.90kg (12.06mol) 2-(2-(4-fluorobenzoyl)phenylamino)-3-(4-(2- (9H-carbazol-9-yl)ethoxy)phenyl)propionic acid was stirred and dissolved at room temperature, and the above-mentioned methanol solution in which sodium hydroxide was dissolved was added to the reaction kettle, and stirring was continued for 30 minutes after the addition was completed. Concentrate in vacuo to remove tetrahydrofuran and methanol to obtain a concentrate. Dissolve the concentrate in 18.29kg of dichloromethane, add it dropwise to 149kg of isopropyl ether at room temperature with stirring, centrifuge, collect the solid, and dry it in vacuum at 105°C for 3 hours to obtain 2-(2-(4-fluorobenzyl Sodium ac...
Embodiment 2
[0045] Example 2: Potassium 2-(2-(4-fluorobenzoyl)phenylamino)-3-(4-(2-(9H-carbazol-9-yl)ethoxy)phenyl)propionate preparation of
[0046]
[0047] Add 0.495g (8.84mmol) KOH and 10mL anhydrous methanol into a 100mL single-necked bottle, stir at room temperature to dissolve. Add 5.00g (8.74mmol) 2-(2-(4-fluorobenzoyl)phenylamino)-3-(4-(2-(9H-carbazol-9-yl)ethoxy Base) phenyl) propionic acid and 150ml tetrahydrofuran, stirring at room temperature to dissolve, adding the above-mentioned methanol solution in which potassium hydroxide was dissolved, and continuing to stir for 30 minutes after the addition. Concentrate in vacuo to remove tetrahydrofuran and methanol to obtain a concentrate. Dissolve the concentrate in 10 mL of dichloromethane, add dropwise to 150 mL of anhydrous diethyl ether at room temperature with stirring, filter, collect the solid, and dry it in vacuum at 60°C for 10 h to obtain 2-(2-(4-fluorobenzoyl) Potassium phenylamino)-3-(4-(2-(9H-carbazol-9-yl)ethoxy...
