Embodiment 1-1
[0116] Example 1-1, Compound (S)-4-(1-(1-(4-(trifluoromethyl)benzyl)-4-methyl-1hydrogen-1,2,3-triazole-5 - Preparation of formamido) ethyl) benzoic acid (YJ001)
[0117]
[0118] Take 4-trifluoromethylbenzyl bromide (717mg, 3mmol) in anhydrous dimethyl sulfoxide (4ml), add sodium azide (215mg, 3.3mmol), and stir at room temperature for 24h. After the reaction was completed, it was extracted with ethyl acetate, and the crude product 4-trifluoromethylbenzyl azide (556 mg, 92%) was obtained after conventional treatment.
[0119] Dissolve 4-trifluoromethylbenzyl azide (556mg, 2.77mmol) in anhydrous toluene (5ml), add ethyl 2-butynoate (224mg, 2mmol), react at 120°C for 12h and cool to room temperature. Most of the solvent was removed under reduced pressure, and after conventional treatment, it was passed through a silica gel column to obtain the intermediate 1-(4-(trifluoromethyl)benzyl)-1H-1,2,3-triazole-4-methyl-5- Ethyl formate (210 mg, 35%).

[0141] Example 1-45, compound (S)-4-(1-(5-(trifluoromethyl)-1-(4-(trifluoromethyl)benzyl)-1H-1,2,3-tri Preparation of azole-4-carboxamido)ethyl)benzoic acid (YJ045)
[0142]
[0143] Take 4-trifluoromethylbenzyl bromide (717mg, 3mmol) in anhydrous dimethyl sulfoxide (4ml), add sodium azide (215mg, 3.3mmol), and stir at room temperature for 24h. After the reaction was completed, it was extracted with ethyl acetate, and the crude product 4-trifluoromethylbenzyl azide (556 mg, 92%) was obtained after conventional treatment.
[0144] Dissolve 4-trifluoromethylbenzyl azide (556mg, 2.77mmol) in anhydrous toluene (5ml), add 4,4,4-trifluoro-2-butyne ethyl ester (332mg, 2mmol), in After reacting at 120°C for 12h, it was cooled to room temperature. Most of the solvent was removed under reduced pressure, and the silica gel column was passed after conventional treatment to obtain the intermediate ethyl 5-(trifluoromethyl)-1-(4-(trifluoromethyl)benzyl)-1H-1,2,3 - Ethyl triazole-4-car...
