A solution of tert-butyl 3-(aminomethyl)-5-(tert-butyldimethylsilyloxy)piperidine-1-carboxylate (4.74 g, 13.7 mmol), 5,7-dichloropyrido[4,3-b]pyrazine (2.75 g, 13.7 mmol) and DIPEA (2.12 g, 16.4 mmol) in THF (20 mL) was stirred at room temperature for 48 hours. The volatiles were removed under reduced pressure and the residue was treated with ethyl acetate, washed with brine, dried over Na2SO4, filtered, and concentrated to give the title compound.
