Sodium Carbonate → HCID 67773555, compound

Participants

Reaction Steps

Under oxygen atmosphere, a mixture of 4-allyl isophthalic acid (500 mg), bis(acetonitrile)dichloropalladium (629 mg), sodium carbonate (514 mg), and THF (30 mL) was stirred at room temperature for 4 hours. The insoluble material of the reaction mixture was separated by filtration, and the filtrate was concentrated under reduced pressure. A mixture of the resulting residue and DMF (5 mL) was diluted with 1M hydrochloric acid, and the precipitate was collected by filtration to obtain 3-methyl-1-oxo-1H-isochromene-7-carboxylic acid (112 mg).
