To a room temperature solution of succinimide (4.22 g, 42.6 mmol, 1.2 equiv.) in anhydrous acetonitrile (89 mL, 0.4 M) was added Hunig's base (12.4 ml, 71.0 mmol, 2.0 equiv.) and 7-(bromomethyl)-4-chloroquinoline-2-carbonitrile (2-4, 10.0 g, 35.5 mmol). The resulting mixture was warmed in the microwave to 100° C. for 1 h. The reaction was then cooled to 0° C. and a precipitate formed. The solids were then collected by vacuum filtration and washed with cold acetonitrile to afford 4-chloro-7-[(2,5-dioxopyrrolidin-1-yl)methyl]quinoline-2-carbonitrile (2-5) which was taken to the next step without further purification. LRMS m/z (M+H)+ 300.2. found, 300.0 required.
