1-(3-Bromo-8-chloro-6,11-dihydro-5H-benzo[5,6]cyclohepta[1,2-b]pyridin-11-yl)-4-[(4-piperidinyl)acetyl]piperazine (Preparative Example 10) (490 mg, 0.8 mmoles) was dissolved in anhydrous dichloromethane (5 ml) and n-propyl isocyanate (322.1 mg, 3.2 mmoles) was added. The mixture was stirred under argon at 25° C. for 44 h. The solution was chromatographed on silica gel using 2% (10% concentrated NH4OH in methanol)dichloromethane as the eluant to give 544.8 mg of the title compound (Yield: 95%).
