実験手順

To a mixture of N-[4-[2-(benzoxazol-2-yl-methyl-amino)-ethoxy]-benzyl]-hydroxylamine (1.5 g, 4.78 mmol) in THF (5 mL) was added acetic anhydride (0.49 g, 4.78 mmol). The mixture was stirred for 1 hour and the volatiles were removed in vacuo. Crystallization from EtOAc/hexane, gave a white solid (1.3 g, 77% yield, m.p. 135°-136° C.).
