실험 절차

To a solution of [6-(4-aminomethyl-phenyl)-pyridin-2-yl]-carbamic acid tert-butyl ester (5.7 g, 19 mmol) and Et3N (2.88 g, 29 mmol) in dichloromethane (50 mL) was added dropwise MsCl (2.7 g, 19 mmol) at 0° C. The reaction mixture was stirred at this temperature for 30 min, and then washed with water and brine, dried over Na2SO4 and concentrated to dryness. The residue was recrystallized with DCM/Petroleum Ether (1:3) to give {6-[4-(methanesulfonylamino-methyl)-phenyl]-pyridin-2-yl}carbamic acid tert-butyl ester (4.0 g, 44% over two steps). 1H NMR (300 MHz, CDCl3) δ 7.90-7.97 (m, 3H), 7.75 (t, J=8.4, 8.4 Hz, 1H), 7.54-7.59 (m, 1H), 7.38-7.44 (m, 3H), 4.73 (br, 1H), 4.37 (d, J=6.0 Hz, 2H), 2.90 (s, 3H), 1.54 (s, 9H).
