80 °C

According to the method described by Lu a solution of catechol (1.0 g) and adamantane diol (0.5 g) in methanesulfonic acid (2 ml) was heated to 80° C. for 3 hours, then left at room temperature overnight. Water was added and the mixture extracted into 10% methanol in chloroform which was dried and evaporated in vacuo to give a white solid. Purification by column chromatography over silica gel eluting with 0-20% methanol in chloroform gave the product as a white solid. Crystallisation from diethyl ether/40% petroleum ether then gave the pure product 10 as a white crystalline solid (210 mg, 20%).
