실험 절차
A mixture of 207 (1.50 g, 4.92 mmol), dibenzylamine (1.45 g, 7.38 mmol), and Et3N (0.75 g, 7.38 mmol) in THF (15 mL) was stirred at room temperature for 48 h. The solvents were evaporated under reduced pressure and the residue was extracted with EtOAc. The EtOAc extracts were washed with water and brine, then dried and evaporated. The residue was purified by chromatography on silica gel eluting with petroleum ether/EtOAc (95:5 then 1:1) to give N,N-dibenzyl-7-bromo-2-naphthalenesulfonamide (208) (2.11 g, 92%). A sample was recrystallised from petroleum ether/EtOAc as colorless crystals: mp 127-129° C.; 1H NMR (CDCl3) δ 8.25 (d, J=1.4 Hz, 1H), 8.05 (d, J=1.6 Hz, 1H), 7.91 (d, J=8.7 Hz, 1H), 7.79 (dd, J1=8.6, 1.8 Hz, 1H), 7.77 (d, J=8.5 Hz, 1H), 7.71 (dd, J=8.8, 1.9 Hz, 1H), 7.22-7.15 (m, 6H), 7.09-7.04 (m, 4H), 4.39 (s, 4H); 13C NMR δ 138.9, 135.4, 133.3, 133.0, 132.1, 131.2, 129.4, 129.3, 128.6, 128.5, 127.8, 127.3, 123.0, 121.6, 50.6.
