Reaction Steps

To 4.89 g of 3,4-dichlorophenol dissolved in a 25 ml THF/25 ml DMSO mixture was added 3.2 g of t-BuOK and then 8.74 g of 2,5-bis((1-methylethyl)sulfonyl)pyridine, and the resulting mixture was heated at 58° C. for 11/2 hrs. The reaction mixture was allowed to cool overnight and then poured in approximately 3 to 4 volumes of water and stirred. The yellow-white precipitate which formed was removed by filtration. Recrystallization from CH2Cl2 /ethanol gave the product, 2-(3,4-dichlorophenoxy)-5-((1-methylethyl)sulfonyl)pyridine, (42% yield), as tiny white needles, m.p. 91°-92° C.
