The invention relates to a process for the manufacture of heptakis-[2,6-di-O-methyl]-beta-cyclodextrin by methylating beta-cyclodextrin in an organic phase wherein beta-cyclodextrin is methylated with dimethylsulfate in the presence of an alkalihydroxide at temperatures of from -10.degree. to 0.degree. C.

Process for the manufacture of

The invention relates to novel aminoacridine-.alpha.,.beta.-(D)- and -(L)-N-glycoside derivatives, the salts thereof and to a novel process for the preparation of such compounds and salts. The novel compounds have the formula I ##STR1## wherein R is hydrogen or a group of the formula II ##STR2## wherein n=0 or 1, p=1 or 2, A.sup.-p is an anion, preferably halogenide, R.sup.1 is hydrogen or a methyl group and
