Reaction Steps

CDI (583 mg, 3.56 mmol) was added to a solution of 4-chloro-3-((4-methoxybenzylamino)methyl) pyridin-2-amine (100 mg, 1.19 mmol) in acetonitrile (5 mL), and stirred for 1 h at room temperature. The resulting precipitate was filtered, and washed with H2O and MeOH, to provide 1 as a solid. LC-MS (M+H=303, obsd.=303. 1H NMR: (DMSO-D6) δ 3.74 (s, 3H); 4.34 (s, 2H); 4.52(s, 2H); 6.92 (d, 2H); 7.03 (d, 1H); 7.26 (d, 2H); 8.03 (d, 1H); 10.08 (s, 1H).
