Under a nitrogen atmosphere, diethoxymethyl acetate (3.0 mL, 18 mmol) was added dropwise to a solution of 7-benzyloxy-N4-(2-phenoxyethyl)quinoline-3,4-diamine (3.0 g, 7.8 mmol) in toluene (30 mL), and the reaction was heated at reflux for three hours. The reaction mixture was concentrated under reduced pressure until a small volume of solvent remained. Hexanes were added, and the resulting mixture was cooled for 20 minutes in a refrigerator. A precipitate formed which was isolated by filtration, washed with hexanes, and dried overnight under reduced pressure to provide 3.12 g of 7-benzyloxy-1-(2-phenoxyethyl)-1H-imidazo[4,5-c]quinoline as a solid.
