Reaction Conditions

Reaction Steps

A mixture of quinolin-6-ylmethanamine (3.6 g, 22.76 mmol), 3,5-dibromopyrazin-2-amine (5.75 g, 22.76 mmol) and triethyl amine (4.61 g, 45.5 mmol) was heated with microwave irradiation at 130° C. for 5 h. The reaction mixture was diluted with CH2Cl2 and water and the organic layer was separated, washed with aqueous NH4Cl, dried over Na2SO4, filtered and concentrated in vacuo. The residue was purified by column chromatography with EtOAc:hexanes to provide 6.93 g (92%) of the title compound. LCMS (method A): [MH]+=330, tR=4.89 min.
