Procedure

0.24 mole (23 ml) of acetic anhydride is added dropwise to a solution of 0.24 mole (72 g) of 5-amino-2-[N-benzyloxycarbonyl-N-(β-hydroxyethyl)amino]phenol in one liter of ethyl acetate heated to 80° C. After evaporation of the solvent under vacuum, the expected product is purified on a silica column. It then melts at 72° C.
