Embodiment 1

[0042] This example describes N-(3-(3-chlorobenzamide)phenyl)-4methoxy-3-nitrobenzamide and its preparation method. The N-(3-(3-chlorobenzamide) The structural formula of carboxamide) phenyl)-4-methoxy-3-nitrobenzamide is as follows figure 1 As shown, the preparation method of this N-(3-(3-chlorobenzamide) phenyl)-4 methoxyl group-3-nitrobenzamide is as follows:

[0043]

[0044] Wherein, the molar ratio of m-phenylenediamine, triethylamine and m-chlorobenzoyl chloride is 1:2:1, 3-nitro-4-methoxybenzoic acid, N,N-diisopropylethylamine, The molar ratio of 1-ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride was 1:2:2.

[0045] Specifically, the preparation method of this N-(3-(3-chlorobenzamide)phenyl)-4methoxy-3-nitrobenzamide is illustrated below:

[0046] Dissolve 2.16 g m-phenylenediamine (20 mmol) in 100 mL of dichloromethane, add 5.5 mL of triethylamine under an ice bath to obtain a mixed solution 1, and dissolve 3.5 g of m-chlorobenzoyl chloride (20 mmol) in 20...

And drying the washed organic phase by anhydrous sodium sulfate, spin-drying, and passing through a column by using silica gel to obtain N-(3-(3-chlorobenzamide) phenyl)-4-methoxy-3-nitrobenzamide. The N-(3-(3-chlorobenzamide) phenyl)-4-methoxy-3-nitrobenzamide provided by the invention can obviously inhibit the activity and proliferation growth of HCT116 and HT29 cells, and can be applied to the preparation of antitumor drugs.

Description

technical field [0001] The invention relates to the technical field of compound synthesis, in particular to N-(3-(3-chlorobenzamide)phenyl)-4methoxy-3-nitrobenzamide and a preparation method and application thereof. Background technique [0002] Colorectal cancer is one of the common tumors in my country, including rectal cancer and colon cancer, and it is also one of the tumors with the fastest increasing incidence in the past two or three decades. 4, 5 or 6, the incidence rate in our country is about 24 / 100,000, and male is slightly higher. With the development of the economy, the improvement of living standards and the change of lifestyle, the incidence rate will continue to rise. [0003] Many colorectal cancer epidemiological studies have shown that there are many factors that cause colorectal cancer, such as dietary factors, occupational factors, physical activity, genetic factors, disease factors and other carcinogenic factors. The occurrence and development of colon...
