Reaction Steps

While a mixture of 10 g of catechol, 50 ml of p-xylene, 25 ml of hexane, 1 ml of phosphoric acid and 0.3 ml of water was heated at 100° C., 7.3 g of isoprene was added dropwise over 10 minutes, and the reaction was further carried out for 7 hours. After cooling, the resulting precipitate was separated by filtration. The filtrate was concentrated, and purified by column chromatography to give 1.7 g (yield 11%) of the product as a pale pink liquid.
