실험 절차

To a solution of 75 mg of 1-tert-butyl-4-[5-(2-chlorophenyl)-1-(2,6-dichlorophenyl)-2-oxo-1,2-dihydro-1,6-naphthyridin-7-yl]-1,2,3,6-tetrahydropyridinium chloride in 3 mL of MeOH and 1 mL of EtOAc was added 35 mg of PtO2 (Adam's catalyst). The mixture was evacuated and purged with N2, then evacuated and purged with H2, then stirred under an H2 balloon for 1 h. The mixture was filtered through Celite, washing with MeOH, and concentrated. The residue was purified by preparative thin-layer chromatography, eluting with 95:5 CH2Cl2-2M NH3 in MeOH, followed by preparative HPLC (YMC C8 19×50 mm column; 10:90 to 90:10 v/v acetonitrile/water+0.05% TFA over 12 min; 20 mL/minute) to yield the title compound. Mass spectrum (ESI) 542 (M+1). 1H NMR (500 MHz, CD3OD): δ 1.40 (s, 9H); 2.04-2.20 (m, 4H); 3.00-3.12 (m, 3H); 3.68 (br d, J=12.5 Hz, 2H); □6.46 (s, 1H); 6.75 (d, J=10 Hz, 1H); 7.48-7.75 (m, 8H).
