Title:
PROCESS FOR PRODUCING 2-ARALKYLPROPIONIC ACID DERIVATIVE
Document Type and Number:
WIPO Patent Application WO/2003/059869
Kind Code:
A1
Abstract:
A process for easily and industrially advantageously producing a high-purity 2-aralkyl-3-acetylthiopropionic acid and a high-purity 2-aralkylpropionic acid having a leaving group in the 3-position from easily available compounds. A 2-aralkyl-1-propanol having a sulfonyloxy group or halogen atom in the 3-position is oxidized with a permanganic acid salt under acidic conditions to produce a high-purity 2-aralkylpropionic acid having sulfonyloxy or the halogen in the 3-position. This acid is reacted with a thioacetic acid salt in the presence of water to produce a high-purity 2-aralkyl-3-acetylthiopropionic acid.
