Synthetic Route of 10320-42-0, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 10320-42-0, name is 2-Chloro-5-nitropyrimidine. This compound has unique chemical properties. The synthetic route is as follows.
first step:A dry 50 mL reaction jar was vacuumed three times with nitrogen.After adding N-methylaniline (107 mg, 1.0 mmol, 1.0 equiv) to the reaction jar,Add 10.0 mL of dried acetonitrile and stir until N-methylaniline is completely dissolved.Then 2-chloro-5-nitropyrimidine (0.1593 g, 1.0 mmol, 1.0 equiv) was added to the reaction flask.The entire mixture was reacted under nitrogen pressure for 4-5 hours.The reaction detects the progress of the reaction by TLC.The reaction can be stopped if it is detected that all the aniline is completely reacted.The experimental treatment is to drain the solution in the reaction;The solute in the reaction flask was dissolved with ethyl acetate.And transferred to a 100 mL round bottom flask,Add 2 mL (200-300 mesh) of silica gel to the round bottom flask for spin-drying (petroleum ether and acetic acid B)Ester) over silica gel in the column.The intermediate product was pale yellow crystals N-methyl-5-nitro-N-phenylpyrimidin-2-amine (197 mg, 86% yield).
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 10320-42-0, 2-Chloro-5-nitropyrimidine.
