For Examples 70-72, the following procedure was used. Under a nitrogen atmosphere, the reagent from the table below (1.5 equivalents) and pyridine hydrochloride (0.01-0.02 equivalents) were added to a solution of tert-butyl {4-[3-amino-6-(benzyloxy)quinolin-4-ylamino]butyl}carbamate (29-36 mmol, 1 equivalent) in toluene (200 mL), and the reaction was heated at reflux for three to five hours. The toluene was removed under reduced pressure. The residue was dissolved in a small amount of toluene, which was removed under reduced pressure. This was repeated three times. The resulting solid was dried under high vacuum at 100° C. to provide the tert-butyl {4-(8-benzyloxy-1H-imidazo[4,5-c]quinolin-1-yl]butyl}carbamate with the substituent indicated in the table below.
