実験手順
To a mixture of 2-(4-(2-methylpyridin-4-yl)phenyl)acetic acid 26-3 (1.1 g, 4.8 mmol), tert-butyl 4-(6-aminopyridin-3-yl)piperazine-1-carboxylate 125-4 (1.3 g, 4.6 mmol) and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluroniumhexafluorophosphate (HATU) (2.0 g, 5.3 mmol) in DMF (15 mL) was added DIEA (2.4 mL, 13.8 mmol) at room temperature. The mixture was stirred at room temperature for 2 hours. The reaction mixture was diluted into ethyl acetate, washed with saturated NaHCO3 then brine, dried over Na2SO4. The solvent was removed by rotary evaporation to give tert-butyl 4-(6-(2-(4-(2-methylpyridin-4-yl)phenyl)acetamido)pyridin-3-yl)piperazine-1-carboxylate 125. MS m/z 488.2 (M+1); 1H NMR 400 MHz (DMSO-d6) δ10.55 (s, 1H), 8.56 (d, 1H), 8.03 (s, 1H), 7.93 (d, 1H), 7.81 (d, 1H), 7.74 (s, 1H), 7.66 (d, 1H), 7.51 (d, 2H), 7.42 (m, 1H), 3.75 (s, 2H), 3.08 (b, 2H), 2.57 (s, 2H), 2.54 (s, 4H), 2.51 (s, 3H), 1.42 (s, 9H).
