Reaction Steps

1,2-Dihydrobenzo[b]pyrrolo[3,2,1-jk][1,2,4]triazolo[4,3-d][1,4]benzodiazepin-8(7H)-one (5.2 g) was dissolved in dimethylformamide (150 ml). Potassium carbonate (0.5 g) was added, followed by (chloromethyl)cyclopropane (2.1 ml). The mixture was stirred at 95° C. overnight, filtered, and evaporated under reduced pressure. The residue was purified by high performance liquid chromatography (1% methanol/dichloromethane) to yield 3.4 g (54.8%) of product. Recrystallization from pentane/ether gave the analytical sample, mp 99° C.
