実験手順

A mixture of 4-((1,4-dimethylpiperidin-4-yl)methoxy)-9H-dipyrido[2,3-b;4′,3′-d]pyrrole-6-carbonitrile (50 mg, 0.16 mmol), N-chlorosuccinimide (60 mg, 0.45 mmol) in acetonitrile (0.8 mL) and isopropyl alcohol (0.23 mL) was stirred at 40° C. for 16 hours. The reaction mixture was diluted acetonitrile (1 mL) and the solid was collected by centrifugation, dissolved in dimethylsulfoxide (2 mL), and purified by preparative HPLC [5-85% methanol in water (0.1% ammonium hydroxide) over 30 min, 35 mL/min] to afford the title compound as a white solid (12 mg, 20%). 1H NMR (500 MHz, d6-DMSO) δ 9.04 (s, 1H), 8.68 (s, 1H), 8.53 (s, 1H), 4.28 (s, 2H), 2.51-2.46 (m, 2H), 2.28 (m, 2H), 2.22 (s, 3H), 1.82 (m, 2H), 1.51 (m, 2H), 1.19 (s, 3H), NH signal not observed. LCMS (Method D): RT=8.445 min, M+H+=370.1.
