The process employed for the removal of {TAIL ~ the C 076 carbohydrate group} or groups is to put the C 076 starting material in solution in a mixture of from {HEAD ~ 0.01 to 10% acid} in a nonnucleophilic water miscible solvent such as dioxane, tetrahydrofuran, dimethoxyethane, dimethylformamide, bis 2 methoxyethyl ether and the like, and from 0.1 to 20% water
