実験手順

2-Benzyloxy-6-bromo-benzo[de]isoquinoline-1,3-dione (0.8 g, 2.1 mmol, from Example M) was reacted in piperidine (3.0 mL) in the presence of DBU (0.05 mL) following the procedure of Example 18 to give 0.8 g of 2-benzyloxy-6-(piperidin-1-yl)-benzo[de]isoquinoline-1,3-dione. Hydrogenation of 2-benzyloxy-6-(piperidin-1-yl)-benzo[de]isoquinoline-1,3-dione (0.4 g, 1.0 mmol) in the presence of 10% Pd/C (0.2 g) in DMA (30 mL) afforded 0.28 g of the title compound, mp 222-224° C.;
