Process for the resolution of racemic (R,S) -5-(2-(2-(2- ethoxyphenoxy) ethylamino)propyl)-2-methoxybenzene sulfonamide (tamsulosin), its novel R and S isomers and their salts and processes for their preparation

An improved process is described to resolve a racemic mixture in any proportion of 5-(2-(2-(2-ethoxyphenoxy)ethylamino)propyl)-2-methoxy benzene sulfonamide as a free base or some of its salts, with BPA either S or R form to obtain enantiomerically highly pure R and S-isomer as a well characterized free base or as a salt of the title compound. Also described are novel R and S-isomers of 5-(2-(2-(2-ethoxyphenoxy) ethylamino)propyl)-2-methoxy benzene sulfonamide and their salts and the processes for their preparation.
