YieldReaction ConditionsOperation in experiment
3.2 g (12.7 mmol, 73%) With sodium hydroxide; In dichloromethane; c. 3,4-Dibromoaniline. 3-Bromoaniline (3 g, 17.4 mmol) was dissolved in 15 ml CH2 Cl2 and the reaction mixture was cooled to -10 C. in an ice-salt bath. 2,4,4,6-Tetrabromo-2,5-cyclohexadienone, (9.29 g, 0.02 mmol) was added in small portions with constant stiting. The reaction mixture was stirred for a period of 7 hours at 0 C. after which the reaction was quenched with 2N NaOH (10 ml). The aqueous layer was extracted with CH2 Cl2 and the organic layer was dried over anhydrous Na2 SO4. The CH2 Cl2 layer was concentrated in vacuo and purified by column chromatography. Elution with 0-3% ethyl acetate/n-hexanes yielded 3.2 g (12.7 mmol, 73%) of pure product; mp 80-81 C.; IR (KBr) 3406, 3318, 3210, 1583, 1464, 1287, 1108, 860, 668; 1 H NMR (CDCl3) 6 6.49 (dd,1H,J=2.7,8.6), 6.7 (d,1H,J=2.64), 7.32 (d,1H,J=8.6); 13 C NMR (CDCl3) 6 112.6, 116, 120.1, 125.45, 134.26, 147.08.
