2,6-Dichlorophenol has been isolated from the females of two species of ticks (Amblyomma americanum and A. maculatum), where it apparently serves as a sex attractant. Each female tick yields about 5 ng of 2,6-dichlorophenol. Assume that you need larger quantities than this and outline a synthesis of 2,6-dichlorophenol from phenol. (When phenol is sulfonated at 100(C, the product is chiefly p-hydroxybenzenesulfonic acid.)
