YieldReaction ConditionsOperation in experiment
22%; 12%; 35% Bromination of 2,4-lutidineTo 2,4-lutidine (5.39 mL, 46.7 mmol, 1 eq.) was added oleum (50 mL, containing 20percent free SO3) carefully under stirring at 0 0C. The reaction flask was fitted with a high-efficiency reflux condenser and heated to 165 °C in an oil bath. Bromine (4.3O mL, 83.4 mmol, 0.9 eq.) was added in portions of 0.5 mL over 5 h, and stirring was continued at 155-175 °C for 20 h. The solution was cooled to room temperature, poured on crushed ice (200 g) and stirred for 1 h. The resulting orange solution was neutralised by careful addition of solid Na2CO3, diluted with water and extracted with EtOAc (2 x 250 mL). The combined organic layers were dried (Na2SO4) and concentrated in vacuo. The crude residue was purified by automated flash column chromatography (Biotage KP-Sil.(TM).

YieldReaction ConditionsOperation in experiment
With bromine; Example 1 Preparation of 5-bromo-2,4-dimethylpyridine STR13 150 ml of 65percent strength oleum are added dropwise to 28.9 ml of 2,4-dimethylpyridine, while cooling with ice and stirring, such that the temperature does not rise above 35° C. When the solution has become homogeneous, 6.42 ml of bromine are slowly added dropwise, with stirring. The mixture is stirred at 80° C. for 31/2 hours. After cooling, it is carefully added dropwise to 1 kg of ice, neutralized with solid Na2 CO3 and extracted 3 times with 300 ml of ether each time. The organic layer is separated off and dried over magnesium sulfate. After removal of the solvent by distillation in vacuo, 34.6 g of a pale yellow oil consisting of the isomers 5-bromo-2,4-dimethylpyridine and 3-bromo-2,4-dimethylpyridine are obtained.

YieldReaction ConditionsOperation in experiment
With bromine; (a) Oleum (65percent, 600 ml) was carefully added to cold 2,4-dimethylpyridine (107.4 g). Bromine (80 g) was added and the mixture was heated for 20 hours at 55°, allowed to cool and poured on to ice. The mixture was neutralised with aqueous sodium hydroxide and extracted with ether. The ether extracts were stirred with ferrous sulphate overnight, evaporated and the residue was distilled to give a mixture of 3-bromo-2,4-dimethylpyridine and 5-bromo-2,4-dimethylpyridine (66.6 g, b.p. 88°-90° at 11 mm Hg).
