The invention provides new process for preparing Carvedilol by reaction of 4-(oxiran-2- yl-methoxy)-9H-carbazole and substituted silyl protected 2-(2-methoxy phenoxy)-ethylamine compound to give silyl protected Carvedilol intermediate. The silyl protected Carvedilol intermediate on desilylation gives Carvedilol. The invention also provides a novel substituted silyl protected 2-(2-methoxy phenoxy)-ethylamine as key intermediate for the preparation of Carvedilol.
