Title: Process for preparing a cyclodextrin derivative

Abstract: A compound of the formula: ##SPC1## Wherein R.sup.2 is mesitylsulfonyl or 2,4,6-triisopropylbenzenesulfonyl and n is an integer of 6 or 7, is reacted with a compound of the formula: R.sup.3 --H wherein R.sup.3 is amino, methyamino, dimethylamino or azido. When R.sup.3 is azido group, the product thus obtained is further subjected to catalytic hydrogenation. A cyclodextrin derivative of the formula: ##SPC2## Wherein R.sup.1 is amino, methylamino or dimethylamino and n is the same as defined above, is obtained. Said cyclodextrin derivative is useful as a hypolipemic agent.
