Versuchsvorschrift

To To a solution of 20 mmol 5-(2-amino-hydroxyethyl)salicylamide and 3.26 g (20 mmol) N-methylanilino acetone in 100 ml methanol add 2.51 g (40 mmol) NaCNBH3. Stir 16 hrs., concentrate, and partition between EtOAc and 1.0 N NaHCO3 solution. Dry and concentrate the organic layer. Dissolve the foam in CHCl3, and wash with water. Filter the solid which forms and recrystallize from EtOAc to give a white solid, mp 143°-5°.
