Trimethyl orthovalerate → 6-(2-butyl-1H-imidazo[4,5-c]quinolin-1-yl)-1-phenylhexan-1-one

Participants

Reaction Steps

A solution of 6-(3-aminoquinolin-4-ylamino)-1-phenylhexan-1-one (2.09 g, 6.25 mmol) and trimethyl orthovalerate (1.52 g, 9.37 mmol) in toluene (50 mL) was heated at reflux under a Dean-Stark trap for 2 hours, then concentrated under reduced pressure to provide 6-(2-butyl-1H-imidazo[4,5-c]quinolin-1-yl)-1-phenylhexan-1-one (2.19 g) as a dark red oil that was used directly in the next step without further purification.
