ABSTRACT:
Two methods are used to produce diaryl trisubstituted triazines. In the first method, cyanuric chloride is first reacted with a 4-alkoxybenzylamine. The product of this reaction is then reacted with a resin-bound amine, such as 4-alkoxybenzylamine, to ensure that the final compound will be bound to a resin. The product of this reaction is then reacted with boronic acid to produce a trisubstituted diaryl triazine. In the second method, cyanuric chloride is reacted with a benzenealkanethiol. The product of this reaction is then reacted with a resin-bound amine, such as 4-alkoxybenzylamine, to ensure that the final compound will be bound to a resin. The product of this reaction is then reacted with m-CPBA to form a sulfone, which is then reacted with a 4-alkoxybenzylamine to form the desired trisubstituted biaryltriazine.
