Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 1813-33-8, name is 2-Chloro-4-(trifluoromethyl)benzonitrile, This compound has unique chemical properties. The synthetic route is as follows., SDS of cas: 1813-33-8
EXAMPLE 17 1′-[4-[1-(4-Fluorophenyl)-5-trifluoromethylindazol-3-yl]-1-butyl]spiro]isobenzofuran-1(3H),4′-piperidine], 17a. To a suspension of magnesium turnings (135 g) in 300 ml of dry tetrahydrofuran, ethyl bromide (140 g) dissolved in 500 ml of dry tetrahydrofuran was slowly added followed by reflux for 20 min. A solution of 4-chloro-1-butanol (274 g) in 500 ml of tetrahydrofuran was added dropwise at reflux temperature. After stirring for 20 min, the Grignard solution was filtered and added portionwise to a solution of 2-chloro-4-trifluoromethyl-benzonitril (200 g) in 600 ml of dry tetrahydrofuran. The reaction mixture was stirred for 16 h at room temperature followed by addition af 2N hydrochloric acid and ice. Extraction with ether, drying of the ether phase over magnesium sulfate and removal of solvent in vacuo left a viscous oil which was applied to a silica gel column (eluent:dichloromethane/ether=3:1) giving 4-(2-chloro-5-trifluoromethylbenzoyl)-1-butanol (101 g) as an oil.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 1813-33-8.
