Water → 6-Hydroxy-4-phenyl-2-propylquinoline-3-carbonitrile

Participants

Reaction Steps

A solution of (2-amino-5-{[tert-butyl(dimethyl)silyl]oxy}-phenyl)(phenyl)methanone (2.0 g, 6.1 mmol), 3-oxohexanenitrile (0.81 g, 7.3 mmol) and methanesulfonic acid (0.59 g, 6.1 mmol) in toluene (50 ml) was stirred at 110° C. for 15 hrs. Water was added to the reaction mixture and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure and the residue was crystallized from disopropyl ether to give 6-hydroxy-4-phenyl-2-propylquinoline-3-carbonitrile (0.98 g, yield 56%) as pale-yellow crystals.
