Reaction Steps

To a solution of 91 (205 mg, 1.0 mmol) in xylene (5 mL) was added trimethyl aluminum (2 M solution in hexanes, 0.75 mL, 1.5 mmol). The mixture was stirred under nitrogen for 10 minutes before the addition of methyl 3-(2-methylquinolin-4-ylamino)benzoate (49) (150 mg, 0.5 mmol). The reaction was heated at reflux overnight, quenched with water (2 mL), basified to pH 9 (2 N NaOH), and extracted with 7:3 CH2Cl2/MeOH. The organic layer was dried (K2CO3) and concentrated under reduced pressure, and the residue was purified by flash chromatography (SiO2, gradient elution) to give 92 as a pale yellow oil (147 mg, 63%).
