Abstract

The present invention relates to a process for preparation of l-(9H-carbazol-4-yloxy)-3- [[2-(2-methoxyphenoxy) ethyl] amino]-2-propanol and its salts comprising; a)reacting 1- (9H-carbazol-4-yloxy)-3-arylmethylamino-2-propanol or its 9-substituted derivatives with 2-(2-methoxyphenoxy)-haloethane; and b) deprotecting the resulting intermediate to obtain l-(9H-carbazol— 4— yloxy)-3-[[2-(2-methoxyphenoxy)ethyl] amino]-2-propanol in free form or its acid addition salt, which are pharmaceutically valuable compounds.
