실험 절차

2-Chloro-4-phenylquinoline was prepared by the following method (Rxn-1). 2-Aminobenzophenone (21 g, 106.5 mmol) was dissolved in methylene chloride (213 mL) and triethylamine (22.3 mL, 159.8 mmol) was added slowly. After cooling to 0° C., acetylchloride (8.3 mL, 117.2 mmol) was added to the reaction mixture dropwise. The reaction mixture was then removed from ice and allowed to stir overnight. Upon the addition of 10% hydrochloric acid (84 mL), the aqueous layers were combined and extracted with ethyl acetate. The organic phases were combined, dried with magnesium sulfate, and concentrated. Purification by column chromatography (25% ethyl acetate/heptane) gave 2-acetamidobenzophenone.
