ABSTRACT OF THE DISCLOSURE Process for preparing esters of 2-(6'-methoxy-2'-naphtyl)- propionic acid via rearrangement of new ketals of 2-halo-1-(6'- methoxy-2'-naphtyl)-propan-1-one in the presence of a Lewis acid. The esters thus obtained are useful as intermediate products for preparing Naproxen.* The process involves the preparation of the following new compounds: ketals of 2-halo-1-(6'-methoxy-2'- naphtyl)-propan-1-one; esters of 2-(5'-bromo-6'-methoxy-2'- naphtyl)-propionic acid; 1-(5'-bromo-6'-methoxy-2'-naphtyl)- propan-1-one; 2-halo (5'-bromo-6'-methoxy-2'-naphtyl)-propan-1-one. *Trade Mark
