Allyl bromide → HCID 86209429, compound

Participants

Reaction Steps

Potassium carbonate (1.6 g, 11.5 mmol) and allyl bromide (1 ml, 11.5 mmol) were added to a solution of trifluoro-methanesulfonic acid 4-formyl-3-hydroxy-phenyl ester (1.55 g, 5.7 mmol) in acetone (50 ml). The reaction mixture was stirred at 55 C for 2 h, filtered and evaporated in vacuo. The residue was chromatographed (silica gel, EA:Hex, 1:20) to give 1.3 g (73%) of trifluoro-methanesulfonic acid 3-allyloxy-4-formyl-phenyl ester.
