Reaction Steps

To a flask charged with 5-bromo-7-methyl-2-benzofuran-1(3H)-one (27 mg, 0.12 mmol) and a stir bar was added allyl tri-n-butyltin (79 mg, 0.24 mmol), lithium chloride (15 mg, 0.36 mmol), palladium tetrakis (28 mg, 0.024 mmol), and toluene (4 mL). The reaction was sealed with a condensor, purged three times with nitrogen, and heated to reflux for 16 hours. LC showed good reaction at that point. The reaction was diluted with EtOAc, adsorbed onto silica gel, and purified by flash chromatography. Removal of solvent gave rise to (7-methyl-1-oxo-1,3-dihydro-2-benzofuran-5-yl)acetaldehyde as a light yellow oil. LC/MS: (IE, m/z) (M+1)+=189.2.
