Procedure

A solution of 2-allyloxy-4,7-dichloro-6-(pyrrolidin-1-yl)benzo[de]isoquinoline-1,3-dione (0.5 g, 1.3 mmol, from Example J4) in trifluoroacetic acid (10 mL) was treated with boron tristrifluoroacetate (6 mL, 6.0 mmol, 1.0 M in trifluoroacetic acid). The reaction mixture was stirred at room temperature for 4 hours and evaporated in vacuo. The residue was chased with dichloro methane and redissolved in methanol which was also evaporated. The residue was partitioned between dichloromethane/water, separated, the organic layer dried, and evaporated in vacuo. The residue was triturated with petroleum ether, the solid removed by filtration, and dried in vacuo to give 0.2 g of the title compound, mp 243-245° C.
