実験手順

A solution of 9-benzenesulfonyl-3-fluoro-5-hydroxy-9H-dipyrido[2,3-b;4′,3′-d]pyrrole-6-carbonitrile (500 mg, 1.36 mmol) and phosphorus pentachloride (708 mg, 3.4 mmol) in chlorobenzene (1.5 mL) was heated at 110° C. for 1 hour. The reaction mixture was cooled to ambient temperature and then the solvent removed in-vacuo to afford a residue. The resultant residue was dissolved in dichloromethane (50 mL) and then the solution was diluted with ice/water (50 mL). The layers were separated and the aqueous layer further extracted with dichloromethane (50 mL). The combined organic layer was washed with brine, dried (Na2SO4), filtered and evaporated. The resultant residue was triturated with diethyl ether and dried to afford the title compound as a tan solid (320 mg, 65%). 1H NMR (400 MHz, CDCl3): 9.81 (s, 1H), 8.69 (d, J=2.8 Hz, 1H), 8.50 (dd, J=7.6, 2.8 Hz, 1H), 8.24 (d, J=8.0 Hz, 2H), 7.65 (t, J=7.5 Hz, 1H), 7.53 (t, J=7.8 Hz, 2H).
