The present invention provides a process for producing a compound having a group represented by general formula (II). (wherein R.sup.1, R.sup.2, and R.sup.3 may be the same or different, and each represent a substituted or unsubstituted alkyl, a substituted or unsubstituted aryl, or a substituted or unsubstituted aralkyl, or R.sup.1 and R.sup.2 may bind to each other to form an alicyclic hydrocarbon ring together with the adjacent carbon atoms, or R.sup.2 and R.sup.3 may bind to each other to form a alicyclic heterocyclic ring together with the adjacent O--C--C that may have a substituent), which comprises allowing a compound having a hydroxyl group to react with halogenated alkyl ether represented by general formula (I): (wherein R.sup.1, R.sup.2, and R.sup.3 are the same as those defined above, respectively and X represents a halogen atom).
