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 in a microwave to 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 silica gel chromatography with EA:Hexanes to provide 6-bromo-N2-(quinolin-6-ylmethyl)pyrazine-2,3-diamine (6.93 g, 92%). LCMS (method A): [MH]+=330, tR=4.89 min.
