Reaktionsschritte

Combine methyl salicylate (5.09 g, 33.2 mmol), sodium carbonate (10.56 g, 99.67 mmol), and 1,3-diiodopropane (29.49 g, 99.67 mmol) in acetone (200 mL). Heat to reflux. After 18 hours, add sodium carbonate (10.56 g, 99.67 mmol) and continue to heat at reflux. After 18 hours, add 1,3-diiodopropane (29.49 g, 99.67 mmol) and continue to heat at reflux. After 18 hours. filter the reaction mixture and concentrate the filtrate in vacuo to give a residue. Chromatograph the residue on silica gel eluting with 1/10 ethyl acetate/hexane to give the title compound: Rf=0.29 (silica gel, 1/10 ethyl acetate/hexane).
