Embodiment 13
[0040] The synthesis of embodiment 13-chloro-4-butoxyaniline
[0041] Phenol potassium salt (0.600g, 2.84mmol), bromo-n-butane (0.501g, 3.70mmol), potassium carbonate (1.96g, 14.2mmol), and 15ml of acetonitrile were added to a three-necked flask and heated to reflux. After the reaction was completed, after a series of The treatment gave 0.540 g of yellow 2-chloro-4-butoxynitrobenzene with a yield of 95.4%. The product obtained by the reaction (0.54, 2.36mmol), iron powder (1.32g, 23.6mmol), ammonium chloride solid (1.62g, 23.6mmol) was added into 15ml of water and methanol mixed solvent into a three-necked flask and heated to reflux. After the reaction was completed, After a series of post-treatments, 0.420 g of the gray product 3-chloro-4-butoxyaniline was obtained, with a yield of 93.0%.
Embodiment 28
[0042] Synthesis of Example 28-(4-amino-2-chlorophenoxy) octanoic acid ethyl ester
[0043]Phenol potassium salt (0.200g, 0.948mmol) and ethyl 8-bromooctanoate (0.308g, 1.23mmol), potassium carbonate (0.601g, 4.34mmol), and 10ml of acetonitrile were added to a three-necked flask and heated to reflux. After the reaction was completed, a series of After post-treatment, 0.28 g of yellow ethyl 8-(2-chloro-4-nitrophenylamino)octanoate was obtained, with a yield of 90.6%. The product (0.28g, 0.816mmol) obtained by the reaction, iron powder (0.457g, 8.16mmol), ammonium chloride solid (0.436g, 8.16mmol) was added into a three-necked flask and heated to reflux with 24ml of water and methanol mixed solvent, after the reaction was completed 0.260 g of the gray product ethyl 8-(4-amino-2-chlorophenoxy)octanoate was obtained through a series of post-treatments, with a yield of 93.5%.
Embodiment 3
[0044] Synthesis of Example 32-(4-amino-2-chlorophenoxy) ethyl acetate
[0045] Phenol potassium salt (0.400g, 1.90mmol), ethyl bromoacetate (0.566g, 2.46mmol), potassium carbonate (1.21g, 8.68mmol), and 15ml of acetonitrile were added into a three-necked flask and heated to reflux for reaction. After the reaction was completed, a series of After post-treatment, 0.46 g of yellow ethyl 2-(2-chloro-4-nitrophenoxy)acetate was obtained, with a yield of 93.9%. The product obtained by the reaction (0.46g, 1.78mmol) and iron powder (0.991g, 17.8mmol), ammonium chloride solid (0.952g, 17.8mmol), 27ml water and methanol mixed solvent were heated to reflux, after the reaction was completed, after After treatment, 0.400 g of ethyl 2-(4-amino-2-chlorophenoxy)acetate was obtained as a gray product, with a yield of 92.2%.
