Versuchsvorschrift

Methyl salicylate (1.7 mL, 0.0131 mol), 1-chloro-2-nitrobenzene (2.30 mL, 0.01965 mol) and potassium carbonate (3.62 g, 0.0262 mol) were mixed in dimethylformamide (35 mL), under argon, at 150° C. for 16 h. The solvent was evaporated and the crude material was flash chromatographed (silica gel, ethyl acetate/hexane). Concentration in vacuo yielded the title compound. 1H NMR (250 MHz, CDCl3) δ8.0 (m, 4H), 7.58 (m, 1H), 7.35 (m, 1H), 7.23 (m, 1H), 7.13 (dd, 1H), 6.85 (dd, 2H).
