Phenyl N-[[(aminocarbonyl)amino]carbonyl]-4-[2-[4-(3-bromo-8-chloro-6,11-dihydro-5 H-benzo[5,6]cyclohepta[1,2-b]pyridin-11-yl)-1-piperazinyl]-2-oxoethyl]-1-piperidine-carboximidate (Formula 16.1) (0.2943 g, 0.462 mmoles) was dissolved in a saturated solution of ammonia in anhydrous THF (80 ml) and the mixture was stirred at 25° C. for 19 h in a sealed vessel. The solution was evaporated to dryness and the residue was chromatographed on silica gel using 3% (10% conc. ammonium hydroxide in methanol)-dichloromethane as the eluant to give the title compound (Formula 17.1) (0.2663 g, 40%), ESIMS: m/z 645.2 (MH+).
