Yield	Reaction Conditions	Operation in experiment
	With iodine; lithium diisopropyl amide; In tetrahydrofuran; diethyl ether; n-heptane; water;	The starting material was prepared as follows: A solution of 3-fluoropyridine (19.4 g) in dry tetrahydrofuran (20 ml) was added dropwise over 30 minutes, under an atmosphere of argon, to a stirred solution of 2M lithium diisopropylamide/tetrahydrofutran/heptane (100 ml) in dry tetrahydrofuran (700 ml) at -70° C. The mixture was stirred at -70° C. for 4 hours. A solution of iodine (50.7 g) in dry tetrahydrofuran (160 ml) was added dropwise to this stirred suspension at -70° C. over 45 minutes and stirring was continued for a further 45 minutes. A mixture of tetrahydrofuran (160 ml)/water (40 ml) was added to the resulting solution at -70° C. The solution was allowed to warm to 0° C. Water (200 ml) was added and diethyl ether (400 ml). The mixture was allowed to stand at ambient temperature for 16 hours. The ether layer was separated. The aqueous layer was extracted with ether (2100 ml). The ether layers were all combined, washed with aqueous sodium thiosulphate solution (2250 ml) and saturated brine (2*100 ml), dried (Na2O4) and evaporated to low bulk. The residue was dissolved in dry diethyl ether and the solution was cooled to -50° C. The solid, which had separated, was filtered off and washed with pentane at -50° C. to give 3-fluoro-4-iodopyridine (22.8 g) as a white solid: NMR (CDCl3): 7.75 (t, 1H), 8.05 (d, 1H), 8.3 5 (s, 1H); m/z 223 M.
