実験手順

In the same way as described in the general procedure for amine displacement using 4-(2-morpholin-4-yl-ethoxy)-phenylamine (600 mg, 2.7 mmol), N,N-diisopropylethylamine (0.470 mL, 2.7 mmol) and a solution of 5,8-dibromo-imidazo[1,2-a]pyrazine (0.500 g, 1.80 mmol) in isopropanol (6 mL). Purification by silica gel column chromatography eluting with a mixture 97:3 DCM:MeOH affords the title compound as a pale yellow solid (650 mg, 86%). 1H-NMR (400 MHz, CDCl3) δ (ppm) 2.51-2.62 (4H, m), 2.75-2.83 (2H, t), 3.71-3.78 (4H, m), 4.09-4.18 (2H, m), 6.90 (2H, d), 7.51 (1H, s), 7.61 (1H, s), 7.64 (2H, d), 7.70 (1H, s), 7.90 (1H, s). LCMS: Rt 2.09 min (97%).
