YieldReaction ConditionsOperation in experiment
2.39 g (94%) With sodium iodide; In acetonitrile; Preparation 9 2-Iodo-6-methylpyridine (10b) To a solution of 2-bromo-6-methylpyridine (2.0 g, 11.6 mmol) and sodium iodide (2.78 g, 18.6 mmol) in dry acetonitrile (13 mL) was added acetyl chloride (1.9 g, 24.4 mmol) dropwise, and the resulting light yellow suspension was heated to reflux. G.C. analysis after 16 hours at reflux indicated only 50percent conversion. Added additional acetyl chloride (1 equivalent) and sodium iodide (0.8 equivalent) and refluxed for 16 hours. G.C. analysis indicated 90percent conversion to desired product in addition to the expected bromo and chloro by-products. The reaction was cooled to room temperature, diluted with aqueous potassium carbonate and sodium bisulfite (75 mL, 10 and 5percent respectively), and extracted with diethyl ether (2*75 mL). The organics were combined, washed with the carbonate/bisulfite solution, dried (sodium sulfate), filtered, and the solvent evaporated under reduced pressure to give 2.39 g (94percent) of crude product as a dark oil. Used without further purification. 1H NMR (CDCl3) delta2.52 (s, 3H,), 7.10 (d, 1H, J=7.51 Hz), 7.20 (t, 1H, J=7.69 Hz, J=7.51 Hz), 7.58 (d, 1H, J=7.69 Hz). (Tetrahedron Lett. 1990, 31, 6757)

YieldReaction ConditionsOperation in experiment
General procedure: Pyridines substituted at the 2-position with halides shown in Tables 2 and 3 are stirred in a mixture of toluene (900 mL) and anhydrous ether (600 mL). The resulting solutions were cooled to < -100 °C for 20 min at which point n-BuLi/hexane was added slowly over 22 min. After maintaining the temperature below -100 °C for 20 min, triisopropylborate was added dropwise, and then the reaction mixture was stirred below -70 °C. After stirring for 4 h, ether (500 mL) was added and the solution was allowed to stand overnight at room temp. Isopropanol was added (30mL), then the reaction mixture was stirred for 30 min, the allowed to stand without stirring for an additional 2 h. The resulting precipitate was collected by filtration then washed with ethyl ether and dried under nitrogen atmosphere for 1.5 h. The resulting triisopropoxy analog was treated with a mixture of acetone and water (450 mL/50 mL) to remove any contaminating n-butylborate lithium salt. The solids were collected by filtration, washed with acetone/water (9:1, 300 mL), and dried in air for 2h, then lyophilized overnight to afford product.
