Reusability of the catalyst was tested in the model reac-
tion. After completion of the reaction in the first run, the cat-
alyst was easily separated from the reaction mixture by using
an external magnet; it was washed twice with ethyl acetate,
dried at ambient temperature and immediately used in the
next step. The reaction was repeated for up to eight consecu-
tive runs without significant change in the efficiency of the
reaction (Figure 7).
