Procedure

To a mixture of 8.5 g (27.2 m mole) of 8-chloro-11-(1-piperazinyl)-6,11-dihydro-5H-benzo[5,6]cyclohepta[1,2-b]pyridine (Preparative Example 7) in 256 mL of anhydrous DMF at room temperature and under an argon atmosphere was added 2.98 g (27.2 m mole of 4-methyl-morpholine, 7.81 g (27.2 m mole) of DEC, 3.68 g (27.2 m mole) of HOBT, and 3.72 g (27.2 m mole) of 4-pyridylacetic acid. The mixture was stirred at room temperature for 22 hours. The mixture was poured into 3300 mL of CH2Cl2 and washed with 500 mL of water. The aqueous layer was extracted with 500 mL of CH2Cl2. The combined organic portions were dried over MgSO4, filtered, and concentrated in vacuo. The residue was purified by silica gel column chromatography using a solution of 1.5% (10% NH4OH in MeOH) in CH2Cl2. The product was obtained as a white amorphous solid, M.S. (Mass Spec) M+=433.
