Reaction Steps

To a solution of pyrrolidine (0.070 g, 0.98 mmol) and triethyl amine (0.11 g, 1.1 mmol) in acetonitrile (5 mL) at reflux was added 2-benzyloxy-6-chloro-5-cyano-benzo[de]isoquinoline-1,3-dione (0.20 g, 0.55 mmol, from Example A2). The reaction was heated at reflux for 20 minutes, then cooled to 0° C. The resulting precipitate was removed by filtration, washed with cold acetonitrile, and dried to give 0.15 g of the title compound.
