Methyl Salicylate → 3-Hydroxyxanthen-9-one

Participants

Reaction Steps

Resorcinol (5.5 g, 50 mmol) and methyl salicylate (11.0 g, 72 mmol) were refluxed for 5 h using a Dean-Stark trap to remove H2O and MeOH. The resulting black oil was chromatographed over silica with 20% ethyl acetate-hexane as eluent. A yellow solid was isolated which was subsequently recrystallized from ethyl acetate to give 1.3 g (12.3%) of 3-hydroxy-9H-xanthen-9-one (lit. mp 242° C.).
