Procedure

A solution of 5.0 g of 3,5-dichlorosalicylaldehyde in 50 ml of DMF was treated with 3.23 g of potassium-tert.-butylate and 6.6 g of allyl iodide and stirred under argon at 65° C. After 2 hours the reaction mixture was concentrated, treated with ice-water and extracted with ethyl acetate. The organic phases were dried over sodium sulphate and concentrated. The residue was chrromatographed over silica gel and gave 5.5 g of 2-allyloxy-3,5-dichloro-benzaldehyde; MS (EI) m/z 230/232 M+.
