1-[8-Bromo-2-(ethoxymethyl)-1H-imidazo[4,5-c]quinolin-1-yl]-2-methylpropan-2-ol (0.550 g, 1.45 mmol), isobutyramide (0.150 g, 1.74 mmol), copper(I) iodide (0.055 g, 0.290 mmol), potassium phosphate (0.647 g, 3.05 mmol), and 1,4-dioxane (1.5 mL) were added to a scintillation vial. 1,2-(±)-trans-Diaminocyclohexane (0.035 mL, 0.290 mmol) was added. The vial was flushed with nitrogen, sealed with a Teflon-lined cap and heated at 110° C. for 72 hours. The vial was cooled to ambient temperature and the reaction was diluted with dichloromethane and methanol. Purification by chromatography with a HORIZON HPFC system (silica cartridge, eluting with a linear gradient of 1-15% CMA in chloroform) provided 0.38 g of N-[2-(ethoxymethyl)-1-(2-hydroxy-2-methylpropyl)-1H-imidazo[4,5-c]quinolin-8-yl]-2-methylpropanamide as a dark semi-solid.
