Reaction Steps

To a stirred suspension of 0.25 g (0.01 mole) of sodium hydride (in mineral oil) in 15 ml of anhydrous dimethylformamide was added, portionwise, 3.05 g (0.01 mole) of 8-chloro-6-phenyl-11H-pyrido[2,3-b][1,4]benzodiazepine. The mixture was warmed at about 60° C. for one hr. A solution of 1.42 g (0.01 mole) of methyl iodide in 10 ml of anhydrous dimethylformamide was added dropwise over a 0.5 hr period and the reaction mixture stirred overnight at room temperature after which it was poured into 400 ml of water and stirred for 2 hr. The precipitated solid was recrystallized twice from isopropyl alcohol to give 2.0 g of product, m.p. 153°-6° C. Drying conditions prior to analyses were 1 hr at 82° C./0.1 mm Hg.
