Procedure

To a solution of 1.77 g of p-aminophenyl-1-thio-β-D-glucopyranoside in 10 ml of water was added 0.9 ml of acetic anhydride. The solution was shaken for 7 minutes, then taken to dryness and evaporated with toluene to a residue. This residue was crystallized from ethyl acetate giving 2.0 g of the desired product, mp. 160°-163° C.
