実験手順

By the general method described in Step 6 of Example 4, a solution of 6-(3-aminoquinolin-4-ylamino)-1-phenylhexan-1-one (2.76 g, 8.25 mmol), trimethyl orthoformate (1.5 g, 9.9 mmol), and pyridine hydrochloride (95 mg, 0.83 mmol) in toluene (26 mL) was heated at reflux under a Dean-Stark trap for 2 hours, then concentrated under reduced pressure to provide 6-(1H-imidazo[4,5-c]quinolin-1-yl)-1-phenylhexan-1-one as a dark oil that was used directly in the next step without further purification.
