실험 절차

tert-Butyl [4-(3-amino-7-benzyloxyquinolin-4-ylamino)butyl]carbamate (20.7 g, 43.6 mmol) was dissolved in toluene (225 mL). Pyridine hydrochloride (2.03 g) and trimethyl orthopropionate (6.2 mL, 43.6 mmol) were added, and the mixture was heated at reflux for 3.25 hours. The reaction was allowed to cool to room temperature; a fine precipitate formed. The precipitate was isolated by filtration and washed with toluene. The off-white solid was allowed to dry for 2 hours under vacuum. The filtrate was evaporated, and the residue was dissolved in dichloromethane. The resulting solution was washed with water and brine, dried over magnesium sulfate, filtered and concentrated under reduced pressure to afford a brown amorphous solid. The solids were combined to provide 17.2 g of tert-butyl [4-(7-benzyloxy-2-ethyl-1H-imidazo[4,5-c]quinolin-1-yl)butyl]carbamate.
