Reaction Conditions

Reaction Steps

A mixture of 6-bromo-2-phenyl-benzo[de]isoquinoline-1,3-dione (4.0 g), sodium hydroxide (0.67 g) and 1,3-propane diol (50 ml) was maintained with stirring at 120° C. for 10 hrs. The reaction mixture was cooled to room temperature. Water (100 ml) was added to the mixture and solid separated out. The solid was filtered, washed with water, and dried at 100° C. for 8 hours to provide a crude product in a yield of 1.90 g. The crude product was purified using mono chloro benzene (60 ml) and activated charcoal (0.20 g). The weight of the of the purified product obtained was 1.15 g. 1H-NMR: 3.93 δ (m, 2 protons); 4.35 δ (m, 1 proton); 2.25 δ (m, 2 protons); 3.96 δ (m, 2 protons); 4.47 δ (m, 2 proton); 7.13 δ (m, 2 protons); 5.14 δ (m, 1 proton); 7.36 δ (m, 3 protons); 7.51 δ (m, 3 protons); 7.84 δ (m, 1 proton); 8.46 δ (m, 2 protons); 8.69 δ (m, 1 proton).
