Abstract

The present invention relates to a process for preparing Tamsulosin, an anti-prostatauxe drug, which comprises converting o-ethoxyphenoxyethanol to the corresponding sulfonate ester, and reacting the sulfonate ester with (R)-(-)-5-(2-aminopropyl)-2-methoxybenzenfulfonamide by condensation to produce Tamsulosin.
