Allyl bromide → 3-Allyloxy-2,6-dichloro-benzaldehyde

Participants

Reaction Steps

2,6-dichloro-3-hydroxybenzaldehyde (960 mg, 5.03 mmol) (Synthesis, 2004, 12, 2062), allyl bromide (431 μL, 5.03 mmol) and potassium carbonate (563 mg, 10.06 mmol) were combined in DMF (5 mL) and stirred at room temperature for 18 hours. The DMF was removed in vacuo and the residue partitioned between diethyl ether (50 mL) and water (30 mL). The layers were separated and the aqueous extracted with diethyl ether (2×30 mL). The combined organic solution was dried over magnesium sulphate and concentrated in vacuo to afford the title compound as a yellow solid which was used without further purification in preparation 75.
