Procedure

DEC (464 mg, 2.42 mmol), HOBT (327 mg, 2.42 mmol), and 4-pyridine-acetic acid (332 mg, 2.42 mmol) were added to 1-(8-chloro-5,11-dihydro-[1]benzothiepino[4,3-b]pyridin-11-yl)-piperazine (400 mg, 1.21 mmol) and NMM (5.3 ml) in DMF (8 ml), and the mixture was stirred at room temperature for 19 hours. Water (30 ml) and EtOAc (50 ml) were added, and the layers were mixed and separated. The aqueous layer was extracted with EtOAc (3×40 ml). The aqueous layer was basified with saturated NaHCO3 and was extracted with CH2Cl2 (2×20 ml). The organic layers were combined, washed with brine, dried (Na2SO4), decanted and concentrated; the crude product (659 mg) was purified by flash chromatography (30%acetone/CH2Cl2 to 5%MeOH/CH2Cl2) and obtained as a white solid (344 mg, 63%); MS (FAB, M+H)=451; HRMS: calc.: 451.1359; found: 451.1355.
