A mixture of diethyl (9-anthracyl)-N-benzylamine-methylphosphonate (0.44 g) and Analar concentrated hydrochloric acid (10 ml) was stirred at gentle reflux for 5 h. Cooled, the solvent was then removed under reduced pressure. Water (10 ml) was added and the solvent was removed under reduced pressure. This was repeated a further four times to give (9-anthracyl)-N-benzylamine-methylphosphonic acid as a white solid (0.4 g), m.p. 168-170° C., λex (EtOH, nm) 332, λem 425.
