Chemistry is traditionally divided into organic and inorganic chemistry. Recommanded Product: 1-(4-Fluorophenyl)-1,3-dihydroisobenzofuran-5-carbonitrile, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 64169-67-1
A process for the preparation of citalopram and the pharmaceutically acceptable salts therof is disclosed by reacting 5-cyanophthalide with a 4-fluorophenyl magnesium halide, reducing the 3-hydroxymethyl-4-(4-fluorobenzoyl)benzonitrile with an agent reducing ketones to alcohols, submitting the thus-obtained 3-hydroxymethyl-4- [(4-fluorophenyl)hydroxymethyl) benzonitrile to a cyclization reaction to give 1-(4-fluorophenyl)-1,3-dihydro-5isobenzofurancarbonitrile without 1,1-bis(4-fluorophenyl)-1,3-dihydro-5- isobenzofurancarbonitrile and treating 1,1-bis(4 fluorophenyl)-1,3-dihydro-5- isobenzofurancarbonitrile with a 3-(dimetylamino)propyl halide in the presence of a base.
If you are interested in 64169-67-1, you can contact me at any time and look forward to more communication. Recommanded Product: 1-(4-Fluorophenyl)-1,3-dihydroisobenzofuran-5-carbonitrile
