Phenol (50 g), zirconium n-propoxide (10 g), and p-cymene (100 ml) were combined. The mixture was distilled through a 10 cm Vigreux column until all volatile components were removed. The cooled product was taken up in a mixture of methylene chloride (100 ml) and toluene (200 ml). This was filtered, and then concentrated under reduced pressure to a volume of ca. 50 ml. The concentrate was filtered to give 6.3 g of solid which was washed with petroleum ether, and dried under high vacuum for one hour to give white solid product.
