실험 절차

Potassium carbonate (113 g) and deionized water (565 mL) were sequentially added to a solution of N-{7-bromo-4-[(2-hydroxy-2-methylpropyl)amino][1,5]naphthyridin-3-yl}-2-ethoxyacetamide hydrochloride (113 g, 261 mmol) in denatured ethanol (1.695 L), and the resulting mixture was heated at reflux (77° C.) overnight and allowed to cool to room temperature. The ethanol was removed under reduced pressure, and the resulting mixture was filtered to isolate a solid. The solid was washed with deionized water (100 mL) and dried over two nights in a vacuum oven at 40° C. to provide 90 g of 1-[7-bromo-2-(ethoxymethyl)-1H-imidazo[4,5-c][1,5]naphthyridin-1-yl]-2-methylpropan-2-ol as a brown solid. Material from a separate run was used in the next step.
