Versuchsvorschrift

A mixture of 1-(2-chloro-ethoxy)-2-nitrobenzene (1.2 g, 6 mmoles) and 1-chloromethane-sulfonyl-naphthalene (2.16 g, 9 mmoles) was stirred in THF (50 ml) at −78° C., in a round bottom flask under nitrogen. A solution of 1M potassium t-butoxide was added drop wise (18 mL, 18 mmoles) over a half an hour period. Temperature was allowed to rise to −40° C., and the reaction mixture was stirred at this temperature for 5 hours. The reaction mixture was poured into cold 2N HCl, extracted with EtOAc, dried over Na2SO4, and concentrated under vacuum. Compound was recrystallized from CH2Cl2/hexane to afford the title compound as an off-white solid (1.4 g, 3 mmoles).
