Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 39989-43-0, name is 3,5-Dichlorobenzylamine, A new synthetic method of this compound is introduced below., Application In Synthesis of 3,5-Dichlorobenzylamine
iV-(3,5-Dichlorobenzyl)-5-fluoro-2-(methylsulfonyl)benzenamine:; A mixture of 2,4-difluoromethylsulfonylbenzene (5.0 mmol), 3,5-dichlorobenzylaniine (5.0 mmol), LambdazetaiV-diisopropylethylamine (10.0 mmol) and acetonitrile (25 mL) was heated at reflux for 18 h, cooled and concentrated in vacuo. The residue was dissolved in ethyl acetate; this solution was washed with water, dried over Na2SO4 and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel using 5 % ethyl acetate in hexanes as eluent to yield the title compounds as a yellowish solid (37 %). 1H NMR (400 MHz, CDCl3): delta 9.28 (br s, 1 H), 7.88 (m, 1 H), 7.34 (s, 1 H), 7.22 (s, 2 H)5 6.44 (m, 1 H)3 6.30 (dd, 1 H), 4.43 (d, 2 H).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
