Procedure

Methyl 2,4-difluorobenzoate (1.53 g), K3PO4 (1.89 g) and 4-hydroxyindole (1.08 g) were stirred at 110° C. in diglyme (12 mL) for 24 hours. The reaction was cooled and poured into ether. The solution was washed three times with 1M aqueous NaOH solution, and brine, and dried over Na_SO4. The solution was then concentrated, and the crude product was chromatographed on silica gel with 20% ethyl acetate/hexanes.
