Embodiment 1

[0213] Example 1, (4-benzyl-[1,4]diazepan-1-yl)-oxo-acetyl (3-allyl- Preparation of 2-hydroxy-methylenephenyl)hydrazine and its salt

[0214] The reaction scheme is outlined as follows:

[0215]

[0216]

[0217] step 1. Under the condition of 0 ℃ and electromagnetic stirring, in the reaction flask equipped with 1.9 g (10 mmol) of 4-benzyl homopiperazine and 1.11 g (11 mmol) of triethylamine and 50 ml of toluene, A solution of 2.0 g (15 mmol) ethyl oxalyl chloride in dichloromethane was added dropwise. After completion of the dropwise addition, stir at room temperature for 8 hours. After the reaction, add 50 ml of water, separate the organic layer, and use Na 2 SO 4 dry. After filtration and concentration, the obtained product was directly used in the next reaction with a yield of 95%.

[0218] Step 2. 2.94 g (10 mmol) of 4-benzyl homopiperazine oxaloethyl ester was added to a 300 ml round bottom flask, and 0.56 g (15 mmol) of 85% hydrazine hydrate was slowly...

Embodiment 2

[0221] Embodiment 2, (4-benzyl-piperidin-1-yl)-oxo-acetyl (2-hydroxyl-methylene phenyl) hydrazine and its salt preparation

[0222] The reaction scheme is outlined as follows:

[0223]

[0224] step 1. Under the condition of 0 ℃ and electromagnetic stirring, in the reaction flask equipped with 1.75 g (10 mmol) of 4-benzylpiperidine and 1.11 g (11 mmol) of triethylamine and 50 ml of toluene, gradually A dichloromethane solution of 2.0 g (15 mmol) ethyl oxalyl chloride was added dropwise. After completion of the dropwise addition, stir at room temperature for 8 hours. After the reaction, add 50 ml of water, separate the organic layer, and use Na 2 SO 4 dry. After filtration and concentration, the obtained product was directly used in the next reaction with a yield of 85%.

[0225] Step 2. 2.75 g (10 mmol) of 4-benzylpiperidine-1-oxaloethyl ester was added to a 300 ml round bottom flask, and 0.56 g (15 mmol) of 85% hydrazine hydrate was slowly added dropwise under ...

Embodiment 3

[0228] Example 3, (pyridine-3-methyl-piperazin-1-yl)-oxo-acetyl (3,5-dichloro-2-hydroxyl- Preparation of methylphenyl) hydrazine and its salt

[0229] The reaction scheme is outlined as follows:

[0230]

[0231] step 1. Under the condition of 0 ℃ and electromagnetic stirring, add 1.77 g (10 mmol) of [4-(1-pyridine-3-methyl)] piperazine- and 1.11 g (11 mmol) of triethylamine In a reaction flask with 50 ml of toluene, 2.0 g (15 mmol) of monoethyl oxalyl chloride in dichloromethane was added dropwise. After completion of the dropwise addition, stir at room temperature for 8 hours. After the reaction, add 50 ml of water, separate the organic layer, and use Na 2 SO 4 dry. After filtration and concentration, the obtained product was directly used in the next reaction with a yield of 90%.

[0232] Step 2. [4-(1-pyridine-3-methyl)]piperazine-1-oxalyl ethyl ester of 2.77 grams (10 mmoles) was added in the round-bottomed flask of 300 milliliters, slowly dripped 0.56 gram...
