Morpholine → 2-Benzyloxy-6-(morpholin-4-yl)-benzo[de]isoquinoline-1,3-dione

Participants

Reaction Steps

2-Benzyloxy-6-bromo-benzo[de]isoquinoline-1,3-dione (0.8 g, 2.1 mmol, from Example M) was reacted in morpholine (3.0 mL) in the presence of DBU (0.05 mL) following the procedure of Example 18 to give 0.6 g of 2-benzyloxy-6-(morpholin-4-yl)-benzo[de]isoquinoline-1,3-dione. Hydrogenation of 2-benzyloxy-6-(morpholin-4-yl)-benzo[de]isoquinoline-1,3-dione (0.4 g, 0.9 mmol) in the presence of 10% Pd/C (0.2 g) in DMA (30 mL) afforded 0.2 g of the title compound, mp 235-237° C.;
