Procedure:
To a solution of 4-fluoro-3,3-dimethyl-1,3-dihydro-2H-indol-2-one (4.1 g) in concentrated sulfuric acid (60 mL) was added dropwise a mixture of fuming nitric acid (0.99 mL) and concentrated sulfuric acid (10 mL) over 30 min at −30° C. The reaction mixture was stirred between −30° C. to 0° C. for 30 min, and poured into ice. The resulting solid was collected by filtration, washed with water, and dissolved in ethyl acetate. The obtained solution was washed with water and saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (2.2 g).

Procedure:
3.75 gms of 1-methyl-2,6-diphenyl-4-oxonicotinic acid was dissolved in 40 mls of methanol. The pH was adjusted to 12 with the addition of aqueous NaOH. A methanolic solution of bromine (2.95 gms Br2 in 50 mls methanol) was added. Additional NaOH was added as required to maintain a basic medium. Removal of the solvent yielded a semisolid that was taken up in 100 mls of water. Water insoluble material was removed by filtration. Acidification of the aqueous solution provided 3.0 gms of 5-bromo-1-methyl-2,6-diphenyl-4-oxonicotinic acid (mp 242°-243°, with decomposition) as a white solid.

Procedure:
2,3,5-Trichloropyridine (9.12 g, 0.050 mol) and 2-ethoxyethanol (5.40 g, 0.060 mol) were dissolved in 50 mL DMSO, followed by portionwise addition of NaH (2.4 g, 60% dispersion in oil, 0.060 mol). The mixture was heated to 80° C. for 3 hours, stirred at room temperature overnight, then heated to 120° C. for 5 hours. The reaction mixture was then diluted to 900 mL with brine, and extracted three times with 100 mL ether. The ether extracts were combined, washed twice with 100 mL water, diluted with 300 mL hexane, filtered through phase-separating paper, and concentrated in vacuo. The residue was purified via silica gel chromatography (first column with 10-50% EtOAc in hexane; second column with 0-10% EtOAc in hexane). Concentration of pure fractions gave 3,6-dichloro-2-(2-ethoxyethyl)pyridine as the major isomer (5.78 g white solid, M.P. 33-34° C.) and 2,3-dichloro-6-(2-ethoxyethyl)pyridine as the minor isomer (1.43 g white solid, M.P. 47-48° C.).
