ABSTRACT:
This invention provides a process for the preparation of glycol 2-(p-chlorophenoxy)-2-methylpropionate nicotinate, of formula (I): ##STR1## which process is characterized in that 2-(p-chlorophenoxy)-2-methylpropionic acid, of formula (II): ##STR2## is reacted with ethylene oxide in an inert solvent in the presence of a catalyst, to prepare the monoglycol ester of the acid (II), of formula (III): ##STR3## which is in turn reacted with nicotinic acid chloride in an inert solvent and in the presence of a base, to prepare the final product, of formula (I).
