In the same way as described in the general procedure for amine displacement using 5,8-dibromo-imidazo[1,2-a]pyrazine (0.534 g, 1.94 mmol), 3-(tert-butyl-dimethyl-silanyloxymethyl)-4-morpholin-4-yl-phenylamine (0.751 g, 2.33 mmol), N,N-diisopropyethylamine (0.31 mL, 1.8 mmol) and iso-propanol (10 mL). Purification by silica gel column chromatography eluting with 7:3 petroleum ether:ethyl acetate followed by trituration with diethyl ether affords the title compound (0.216 g, 17%).
