Yield: 75%
Reaction Conditions:
with aluminum (III) chloride in chlorobenzene at 125; for 2 h;
Steps:
39.b
(b) 8-Bromo-2(1H)-quinolinone To a suspension of (2E)-N-(2-bromophenyl)-3-phenyl-2-propenamide (22.9 g, 76.0 mol) in chlorobenzene (100 ml) under an argon atmosphere at room temperature was added aluminium trichloride (60.78 g, 133.34 mmol). The reaction was heated for 2 hours at 125° C. after which time the reaction mixture was cooled to 50° C. before being carefully added to ice water (3 L). The resultant solid was filtered and then washed with water (500 ml), then triturated with hot ethanol, filtered and dried in vacuo to provide the desired compound as a white solid (7.39 g, 75%). MS (ES+) m/z 225 (MH+, 100%).
