Procedure

The method described in Part C of the preparation of 1-[4-amino-7-bromo-2-(ethoxymethyl)-1H-imidazo[4,5-c][1,5]naphthyridin-1-yl]-2-methylpropan-2-ol was used to treat tert-butyl 2-[(3-amino-7-bromo[1,5]naphthyridin-4-yl)amino]-1,1-dimethylethylcarbamate (64.0 g, 0.156 mol) with ethoxyacetyl chloride (21.0 g, 0.171 mol) in acetonitrile (640 mL). At the completion of the reaction, additional acetonitrile (200 mL) was added, and the solid product was isolated by filtration, washed with a small volume of acetonitrile, and dried for four hours to provide 55.6 g of tert-butyl 2-({7-bromo-3-[(ethoxyacetyl)amino][1,5]naphthyridin-4-yl}amino)-1,1-dimethylethylcarbamate hydrochloride.
