The present invention provides an improved process for the preparation of 4-((2-isopropoxy ethoxy) methyl) phenol compound (I), used as an intermediate in many organic synthesis particularly a key intermediate for the synthesis of l-[4[2(l-methylethoxy) ethoxy methyl] phenoxy]-3-(l-methylethylamino)-propan-2-ol commonly known as Bisoprolol or its pharmaceutical acceptable salts. The process comprises reacting the 4-hydroxybenzyl alcohol (II) with the 2-isopropoxyethanoI (III) in the presence of activated silica and optionally, in the presence of solvent.
