Summary:PURPOSE: Provided is a method for converting a substituted or unsubstituted solid supported trityl alcohol to the substituted or unsubstituted solid supported trityl chloride, wherein the functionalized solid supports is useful in water treatment for municipalities, private homes and public buildings such as schools and hospitals, and in the semiconductor industry where ultra high purity water is an issue. CONSTITUTION: The method comprises the steps of (a) dispersing an organic solvent and a substituted or unsubstituted trityl solid supported alcohol in a reaction vessel, (b) adding 0.00001 to 1.00 equivalents of an amide containing catalyst compound to the reaction vessel, (c) adding a halogenating agent to the reaction vessel, and (d) filtering and draining the result of steps (a), (b), and (c) to obtain the substituted or unsubstituted trityl chloride solid support. The organic solvent is selected from the group consisting of dichloromethane, toluene, dichloroethane, and tetrahydrofuran, and mixtures thereof.
