Embodiment 1
[0041] Prepare active ingredient, this active ingredient is made by following steps:
[0042] Step S1: Add p-toluic acid and methanol into the flask, then slowly dropwise add sulfuric acid solution with a mass fraction of 70%, reflux for 12 hours, then distill off excess methanol solution under reduced pressure, then add distilled water, use dichloromethane Extracted 3 times, dried over anhydrous magnesium sulfate, and distilled under reduced pressure to obtain intermediate 1; the dosage ratio of p-toluic acid, methanol, and sulfuric acid solution was 0.1mol: 80mL: 2mL;
[0043] Step S2: add intermediate 1 to hydrazine hydrate with a mass fraction of 80%, stir and react at room temperature for 11 hours, and dry to obtain intermediate 2 after the reaction; the ratio of intermediate 1 and hydrazine hydrate is 0.08mol : 30mL;
[0044] Step S3: Add intermediate 2, carbonamide and deionized water into the flask, and reflux reaction at a temperature of 100° C. for 8 hours to obtain...

[0051] Step S2: add intermediate 1 to hydrazine hydrate with a mass fraction of 80%, stir and react at room temperature for 12 hours, and dry to obtain intermediate 2 after the reaction; the ratio of intermediate 1 and hydrazine hydrate is 0.08mol : 30mL;
[0052] Step S3: Add intermediate 2, carbonamide and deionized water into the flask, and reflux reaction at a temperature of 100° C. for 9 hours to obtain...
Embodiment 3
[0057] Prepare active ingredient, this active ingredient is made by following steps:
[0058] Step S1: Add p-toluic acid and methanol into the flask, then slowly dropwise add sulfuric acid solution with a mass fraction of 70%, reflux for 12 hours, then distill off excess methanol solution under reduced pressure, then add distilled water, use dichloromethane Extracted 3 times, dried over anhydrous magnesium sulfate, and distilled under reduced pressure to obtain intermediate 1; the dosage ratio of p-toluic acid, methanol, and sulfuric acid solution was 0.1mol: 80mL: 2mL;
[0059] Step S2: add intermediate 1 to hydrazine hydrate with a mass fraction of 80%, stir and react at room temperature for 13 hours, and dry to obtain intermediate 2 after the reaction; the ratio of intermediate 1 and hydrazine hydrate is 0.08mol : 30mL;
[0060] Step S3: Add intermediate 2, carbonamide and deionized water into the flask, and reflux at a temperature of 100° C. for 10 h to obtain intermediat...
