Abstract
(EN)
The present invention provides a process for the preparation of (1S)-2,3,4,6-tetra- O-acetyl-1,5-anhydro-1-[3-[[5-(4-fluorophenyl)-2-thienyl]methyl]-4-methylphenyl]-D- glucitol of Formula III. The invention also provides a process for the purification of canagliflozin using (1S)-2,3,4,6-tetra-O-acetyl-1,5-anhydro-1-[3-[[5-(4-fluorophenyl)-2-5 thienyl]methyl]-4-methylphenyl]-D-glucitol of Formula III.
