Reaction Steps
A mixture of (1H-pyrrolo[2,3-b]pyridin-3-yl)methanamine (intermediate A) (442 mg, 3.0 mmol), 3,5-dibromopyrazin-2-amine (758 mg, 3.0 mmol) and N-ethyl-N-isopropylpropan-2-amine (1160 mg, 9.0 mmol) in EtOH (70 mL) was stirred at 150° C. overnight. After being cooled to room temperature, it was concentrated and purified by chromatography to afford the title compound (70 mg) MS (m/z): 319 (M+1)+.
