실험 절차

A solution of the compound obtained in Step D (2.1 g) and N-bromo-succinimide (2.56 g) in acetonitrile (50 ml) was stirred at 0° C. for 10 minutes. The reaction mixture was poured into water and extracted several times with ethyl acetate. The combined organic layers were washed with brine, dried over sodium sulfate and then concentrated in vacuo. Chromatography on silica gel (eluent: hexane/ethyl acetate 1:1) afforded 2-bromo-6-difluoromethyl-pyridin-3-yl-amine (2.5 g) as a solid. MS (ES+) 223/225 (MH+); 1H NMR (400 MHz, CDCl3) 4.38 (br s, 2H), 6.52 (t, 1H), 7.08 (d, 1H), 7.41 (d, 1H).
