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...
