반응 단계
In the same way as described for compound 90, step 1, using 5,8-dibromo-imidazo[1,2-a]pyrazine (0.4 g, 1.45 mmol), 5-morpholin-4-yl-pyridin-2-ylamine (0.258 g, 1.23 mmol), NaOtBu (0.19 g, 2.04 mmol), Pd2dba3 (0.053 g, 0.058 mmol) and Xantphos (0.067 g, 0.116 mmol) in toluene (6 mL). After removing the solvent in vacuo, the mixture is purified by silica gel column chromatography eluting with 1:4 petroleum ether:ethyl acetate followed by 99:1 DCM:NH3 (7M in MeOH). The title compound is isolated (216.4 mg, 47%). LCMS: Rt 2.16 min (93.2%).
