실험 절차

To the stirred solution of 8-((2-amino-2,4-dimethylpentyl)oxy)-4,6 dimethylbenzo[c][2,7]naphthyridin-5(6H)-one (Prepared in Example 32, Part B) (0.08 g, 0.226 mmol) in acetonitrile (5 mL) was added NCS (0.030 g, 0.226 mmol)) at RT and the reaction mixture was stirred for 2 h. The mixture was then evaporated to dryness. The residue was purified by reverse phase HPLC (0.1% TFA in water/AcCN) to afford 8-((2-amino-2,4-dimethylpentyl)oxy)-9-chloro-4,6-dimethylbenzo[c][2,7]naphthyridin-5(6H)-one (12 mg, 0.030 mmol, 13% yield). LC/MS (ESI) m/e 388.0 [(M+H)+, calcd for C21H27ClN3O2, 388.2] as an off-white solid. LC/MS retention time (method C): tR=2.13 min. HPLC retention time (method A): tR=8.97 min; HPLC retention time (method B): tR=10.16 min. 1H NMR (400 MHz, METHANOL-d4) δ ppm 0.99-1.02 (m, 6H), 1.30 (s, 3H), 1.54-1.66 (m, 2H), 1.84-1.90 (m, 1H), 3.05 (s, 1H), 3.73 (s, 1H), 4.04 (q, J=23.20 Hz, 2H), 7.03 (s, 1H), 8.06 (d, J=6.00 Hz, 1H), 8.39 (s, 1H), 8.54 (d, J=6.00 Hz, 1H).
