반응 단계
A mixture of (6-chloro-pyrimidin-4-yl)-methyl-amine (1 g, 7 mmol), 2-nitro-phenylamine (965 mg, 7 mmol), Brettphos (279 g, 0.35 mmol) and tBuONa (2 g, 21 mmol) in DME (50 mL) was heated to 90° C. for 1 hour under nitrogen atmosphere. The reaction was concentrated, and the residue was purified by flash chromatography on silica eluting with DCM:EtOAc=10:1-4:1 to obtain the title compound (600 mg, yield: 35%) as a yellow solid. 1H NMR (400 MHz, CDCl3) δ 2.94 (d, 3H), 4.99 (bs, 1H), 5.82 (s, 1H), 7.04 (t, 1H), 7.60 (t, 1H), 8.21 (d, 1H), 8.33 (s, 1H), 8.75 (d, 1H), 9.91 (s, 1H); MS (ESI): 246 [M+H]+.
