Procedure

A 100 ml autoclave was charged wtih 20 g of resorcinol, 12 g of butadiene, 4 ml of H3PO4 and 60 ml of toluene, and purged with nitrogen. The mixture was then heated at 100° C. for 3.5 hours. The crude product was purified by column chromatography to give 24.1 g (yield 82%) of the desired product as a brown liquid.
