PROCESSES FOR THE PREPARATION OF (E)-2-FLUOROMETHYLENE-4-(4-FLUOROPHENYL) BUTYLAMINE AND ALKALI METAL SALTS OF DIFORMYLAMIDE
摘要:
The present invention relates to a novel process for preparing (E)-1-amino-2-(fluoromethylene)-4-(p-fluorophenyl)butane, also known in the art as (E)-(p-fluorophenethyl)-3-fluoroallylamine, novel intermediates thereof, a novel process for the preparing (E)-2-(fluoromethylene)-4-(p-fluorophenyl)butan-1-ol, a novel process for preparing alkali metal salts of diformylamide, and a novel crystalline form of sodium diformylamide.
