Reaction Steps

Heat a slurry of 7-(2,5-dihydro-4-imidazo[1,2-a]pyridine-3-yl-2,5-dioxo-1H-pyrrol-3-yl)-9-fluoro-1,2,3,4-tetrahydro-2-(1-piperidinyl-carbonyl)-pyrrolo[3,2,1-jk][1,4]benzodiazepine ethanolate (198.5 mg) in water (10 mL) to 80° C. for 2.75 hours. Add 3.11 mL of 1N HCl. When the temperature has returned to 80° C., rapidly add 3.11 mL of 1N NaOH. Allow the temperature to remain at 80° C. for approximately 15 minutes then allow the suspension to cool to room temperature. Collect the solid using vacuum filtration through Whatman #1 paper and allow to dry loosely covered over night. Powder X-ray Principal Peaks (Degrees 2 Theta, Intensity): 12.089°, 100%; 10.485°, 83.6%; 13.227°, 56.0%; and 7.660°, 8.0%.
