Reaction Steps

To a stirred suspension of 0.56 g (0.023 mole) of sodium hydride in 25 ml of anhydrous dimethylformamide was added, portionwise, 5.0 g (0.0184 mole) of 6-phenyl-11H-pyrido[2,3-b][1,4]benzodiazepine. The reaction mixture was warmed to 80°±2° C. for 1 hr and cooled to room temperature. A solution of 5.55 g (0.020 mole) of N-(3-bromopropyl) phthalimide in 10 ml of anhydrous dimethylformamide was added dropwise and after stirring for 16 hr the reaction mixture was poured into 650 ml of water and stirred for 30 min. The yellow solid was collected by filtration and recrystallized three times from isopropyl alcohol to give 3.7 g of product, m.p. 170°-172° C.
