Abstract

This invention relates to a manufacturing process for the preparation of bisoprolol and its pharmaceutically acceptable salt as well as its intermediates. The intermediate 4-[(2-isopropoxyethoxy)methyl]phenol is prepared by reaction of 4-hydroxybenzyl alcohol with 2-isopropoxy ethanol in presence of Amberlyst 15 in high yield with high purity.
