Under anhydrous conditions, 4-dimethylaminopyridine (DMAP,340 mg, 2.8 mmol, 2.5 equiv), N-(3-dimethylaminopropyl)-N?-ethylcarbodiimide hydrochloride (EDC¡¤HCl, 640 mg, 3.4 mmol,3.0 equiv), and 3-aminoquinoline (450 mg, 3.1 mmol, 2.8 equiv)were added as solids to a suspension of compound 3 (3.0¡¤102mg, 1.1 mmol, 1.0 equiv) in DMF (23 mL). The solution wasplaced under argon and stirred at room temperature (48 h). Theresulting yellow suspension was filtered under vacuum, and theisolated precipitate washed with saturated aqueous sodiumbicarbonate (30 mL), CH2Cl2 (20 mL), and diethyl ether (20 mL)to afford pure compound 4 as a pale yellow solid (490 mg, 85percent).1H NMR (300 MHz, DMSO-d6): delta = 7.68 (t, 3J = 7 Hz, 2 H), 7.75 (t,3J = 7 Hz, 2 H), 8.09?8.13 (m, 4 H), 8.33 (s, 2 H), 8.69 (d, 3J = 8 Hz,2 H), 8.91 (d, 3J = 8 Hz, 2 H), 9.17 (d, 4J = 2 Hz, 2 H), 9.68 (d, 4J = 2Hz, 2 H), 11.88 (s, 2 H); mp >280 ¡ãC (lit. >260 ¡ãC).7, 57709-61-2
