Procedure
2-Benzyloxy-5-methoxy-6-bromo-benzo[de]isoquinoline-1,3-dione (0.5 g, 1.2 mmol, from Example Z) was reacted in piperidine (3 mL) in the presence of DBU (0.05 mL) following the procedure of Example 18 to give 0.3 g of 2-benzyloxy-5-methoxy-6-(piperidin-1-yl)-benzo[de]isoquinoline-1,3-dione. The hydrogenation of 2-benzyloxy-5-methoxy-6-(piperidin-1-yl)-benzo[de]isoquinoline-1,3-dione (0.3 g, 0.7 mmol) was performed as described in Example 18 to give 0.17 g of the title compound, mp 204-205° C.;
