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 (200.8 mg) in water (25 mL) to 75° C. for 0.67 hours. Add 0.72 mL of 1N HCl and continue to heat for 1.75 hours. Add 0.1N NaOH in 1 mL increments every 5 minutes until 7.2 mL have been added. After the last addition, allow the suspension to remain at 75° C. for 0.67 hours and then allow the suspension to cool to room temperature. Collect the solid using vacuum filtration through Whatman #1 paper, rinse with 20 mL deionized water and allow to dry loosely covered for 2 days.
