Chemistry is traditionally divided into organic and inorganic chemistry. Computed Properties of C15H10FNO, 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
PROCESS FOR PREPARING 5-SUBSTITUTED -1-(4-FLUOROPHENYL) -1,3-DIHYDROISOBENZOFURANS
The present invention relates to a method for preparation and isolation of hitherto unknown solid boron complex of formula (v), which are obtained when 5-substituted phthalides are reacted with a solution of 4-fluorophenylmagnesiumbromide, followed by in situ reduction and complex formation in the presence of sodiumborohydride. Such boron complexes can be conveniently filtered to remove structurally similar impurities and subsequently subjected to cyclisation reaction in acidic medium to get high pure 5-substituted phthalens, which are key starting materials for manufacturing citalopram and pharmaceutically acceptable acid addition salts.
