Reaction Steps

2-{4-[4-amino-2-ethoxymethyl-1-(3-isopropoxypropyl)-1H-imidazo[4,5-c]quinolin-7-yl]butyl}-1H-isoindole-1,3(2H)-dione (1.15 g, 2.1 mmol) was dissolved in ethanol (36 mL. Hydrazine (0.372 mL, 11.4 mmol) was added and the solution was heated at reflux temperature for 1 hour. The resulting white slurry was cooled to ambient temperature and filtered. The solid showed 40% product by NMR. The solid was saved and used in Part E. The filtrate was concentrated under reduced pressure and purified using a HORIZON HPFC system (silica cartridge, eluting with a linear gradient of 2-20% CMA in chloroform) to provide 0.211 g of 7-(4-aminobutyl)-2-ethoxymethyl-1-(3-isopropoxypropyl)-1H-imidazo[4,5-c]quinolin-4-amine as a white solid.
